The six-party agreement reached last week in Beijing to cap North Korea's nuclear program was a triumph for diplomacy. But contrary to much of the conventional wisdom in recent days, the fruits of the victory fall mostly to the North Koreans.

In the short term, the deal will halt the country's production of nuclear materials, limiting its ability to expand a nuclear arsenal tested in October. But for this concession, the North Koreans get to keep that arsenal intact, at least for now, and stand to make significant economic and political gains in relations with the United States, China and South Korea.

Some critics say the Beijing agreement is a lesser version of "the Agreed Framework" reached in 1994 by the Clinton administration, later cast aside by President Bush. Former Clinton-era Defense Secretary William Perry, speaking Tuesday at the Asia Society, characterized the new agreement as "thin gruel," while backing it as "a small but a very important step forward."

The ultimate judgment will await the uncertain implementation of numerous crucial, but still vaguely defined, steps down the road. The North Koreans are certain to exploit every ambiguity in the text and to drag out the phase that calls for actual dismantlement of their nuclear program and weapons.

Unfortunately, the process that led to this moment suggests that this will not go well. Contrary to the administration's version of events, Pyongyang was not dragged to this deal by pressure -- not from Washington and not from North Korea's angry patrons in Beijing.

"We don't have the North Koreans on the ropes," a former senior U.S. intelligence analyst who has watched that closeted country for decades said. "We don't have them on the run."

On the contrary, there is ample evidence that this agreement is yet another demonstration of North Korea's uniquely successful brand of negotiation via escalation: a use of brinkmanship and willingness to go up to and over the line that converts weakness into leverage.

Against that approach, the Bush administration's preference for using tools of coercion and threat, even of pre-emptive war, failed. If anything, it brought about the very opposite outcome than the United States envisioned: it encouraged North Korea to move even more rapidly to develop and test a nuclear weapon.

The pattern of brinkmanship was already clear during the Clinton years -- what Korea expert Scott Snyder famously termed "negotiating on the edge." When confronted, Snyder noted, the North Koreans typically responded by accelerating the crisis, unworried by the consequences. The fear of appearing weak has underlined all North Korean behavior.

The Bush administration came into office almost seeking a confrontation, as the president and many of his advisers were convinced the 1994 deal was fatally flawed. Ironically, the North Koreans thought they were on the verge of strategic breakthrough, after a deal to halt missile tests and preparations for President Clinton to visit Pyongyang in the final weeks of his administration. An improved relationship with the United States would balance the power of its Chinese patron, whom North Korea deeply distrusts, and give it legitimacy in an ongoing struggle with South Korea for leadership on the Korean peninsula.

Instead Bush froze the Clinton framework and sought a new, tougher approach. In January 2002, Bush delivered his famous State of the Union depiction of North Korea as a member of the "axis of evil," along with Iran and Iraq. That October, U.S. negotiators confronted Pyongyang with accusations of cheating by pursuing a clandestine uranium-enrichment program.

The 1994 agreement collapsed amid a tit-for-tat series of escalatory moves -- beginning with a U.S. cutoff of heavy fuel oil and leading to North Korea ousting international inspectors, withdrawing from the Nuclear Non-proliferation Treaty and restarting its reactor and recycling facility to produce plutonium. Bush vowed that the United States would not "be blackmailed."

Meanwhile, preparations for war in Iraq were mounting. The Bush administration was convinced the awesome display of U.S. power would successfully intimidate the other two points on the axis of evil, North Korea and Iran.

"We are hopeful," then senior State Department official John Bolton dryly said as the invasion came to a close, "that a number of regimes will draw the appropriate lesson from Iraq -- that the pursuit of weapons of mass destruction is not in their interest."

American threat

The North Korean officials drew an entirely different conclusion: they could not afford to seem weak in the face of what they perceived as an American threat to terminate their regime.

"Only tremendous military deterrent force powerful enough to decisively beat back an attack supported by ultra-modern weapons can avert a war and protect the security of the country," said an official statement issued April 6. "This is the lesson drawn from the Iraqi war."

A drawn-out process of negotiations began later that month, beginning with a three-way meeting in China and moving that summer to six-party talks that also included South Korea, Japan and Russia. The U.S. position was to deny Pyongyang what it wanted most -- direct talks with Washington -- and to demand verified dismantlement of its nuclear program, on the model of Libya, before any rewards, economic or political, were provided.

As the war in Iraq wore on, and the threat of military force became less credible, the administration looked for other coercive tools. It forged a multinational agreement to intercept suspicious cargoes and launched a crackdown on illicit North Korea trafficking in drugs and counterfeit currency and goods, which are believed to be the main source of support for the regime's elite.

The North Koreans countered with their own demands, offering a plan to freeze their nuclear program, with compensation, followed by a coordinated series of reciprocal steps leading toward eliminating the program. Their offers were accompanied by statements that they already had the bomb and were prepared to test it.

When the Bush administration started its second term in 2005, it attempted to escalate pressure -- this time with charges that North Korea was exporting nuclear materials to the Middle East and calls for China to put pressure on its difficult clients. Pyongyang moved to unload a second set of spent fuel from its reactor and reprocess it -- American experts believe North Korea created six to eight bombs worth of plutonium after 2002.

Agreement sours

A return to the bargaining table in September 2005 yielded an agreement on the principles that would underlie a denuclearization of the Korean peninsula. But that sign of progress disappeared within hours as both sides sparred over the meaning of a pledge to build nuclear power reactors for North Korea as compensation for it dismantling its nuclear weapons.

The imposition of measures to curb the flow of North Korean "illicit" money through Chinese and other banks added to the acrimony. Administration officials described this as a legal issue driven by Treasury Department efforts to curb counterfeiting. But as Bush admitted recently, it was used as leverage in the nuclear talks.

Throughout the past year, Bush administration officials expressed confidence that these measures were causing serious pain to the North Korean leadership. Some even talked boldly of "turning out the lights" in Pyongyang through such sanctions.

But Pyongyang could read the news from Iraq as well as any American voter. Instead of having its lights turned out, North Koreans put up their own light shows. On July 4, a date chosen with apparent intent, they carried out a test of a battery of ballistic missiles, in defiance of warnings, including one from China. A U.N. resolution condemning the action -- and other steps, including a South Korean suspension of food and fertilizer aid and Chinese attempts to slow trade -- followed.

In October, again in defiance of pressure from all fronts, the North Koreans tested a nuclear device. This prompted another U.N. resolution, backed by China, to impose limited economic sanctions. But although China was clearly angered, there is little evidence it moved to cut off the lifeline of trade, particularly energy supplies.

North Korea's willingness to cross what everyone believed was a "red line" changed the equation permanently. It allowed Pyongyang to return to the six-party talks, stalled for more than a year, but now from a position of strength. At the meeting in December, the North Koreans refused to discuss any other issues unless the U.S. financial sanctions were removed. North Korean officials hinted of preparations for a second test.

The United States blinked, agreeing to hold long-sought direct talks, held in Berlin in mid-January. The talks yielded the outlines of the Beijing deal but also a separate U.S. concession to lift the financial measures within 30 days of signing a broader deal.

The Beijing agreement more closely resembles North Korea's June 2004 freeze proposal than it does the U.S. insistence that dismantling nuclear weapons precede any substantial rewards. Clearly, this is a deal the Bush administration would not have made, says Scott Snyder, "if it were not tied down with so many other problems."

North Korea made its own concessions in the Beijing agreement. But "it doesn't necessarily mean Pyongyang is backing down or preparing to abandon its nuclear weapons," argues Kim Sung Han, a senior analyst at the South Korean Foreign Ministry's research institute.

N. Korea's rewards

Administration officials point out that the initial freeze of North Korea's nuclear program, to be implemented in two months, yields only minor compensation, about 50,000 tons of heavy fuel oil. But that is not what Pyongyang sees as its real reward. The lifting of financial measures will facilitate its rapidly growing trade with China and South Korea. Even more important, the South Korean government has already signaled it will now lift the ban on large-scale fertilizer and food shipments -- which are crucial to North Korea's spring planting.

Less visible, but no less vital, the North Koreans are trying to hold off a conservative comeback to power in the South Korean presidential election in December. A North-South summit meeting may take place, which would be part of an effort by the progressive South Korean government to shore up its support.

Ultimately, the Beijing agreement may yield a trade of nuclear facilities for economic and political relations, leaving the nuclear arsenal capped but still intact. For some U.S. experts, that is sufficient.

"It will limit the size of the nuclear arsenal and the amount of bomb fuel," observes former Los Alamos nuclear laboratory director and Stanford scholar Siegfried Hecker. And that, he says, should make it less likely North Korea would sell its nuclear materials or expertise to Iran.

The bargain made in Beijing flows inexorably from North Korea's skillful playing of the escalation game. But it may be the best outcome possible, given that North Korea has already crossed the nuclear threshold and that the Bush administration has squandered U.S. power in the deserts of Iraq.

Executive Summary

The first Korea - West Coast Strategic Forum held in Seoul on December 11-12, 2006, convened policymakers, scholars and regional experts to discuss the North Korean nuclear issue, the state of the U.S.-ROK alliance, and notions of a formalized mechanism for security cooperation in Northeast Asia. Participants engaged in lively and frank exchanges on these issues. Gi-Wook Shin, Daniel C. Sneider, Siegfried S. Hecker, and Kristin C. Burke represented the Freeman Spogli Institute.

Participants were concerned that North Korea's drive toward nuclear weapons has exposed disparate interests among the five parties committed to arresting this ambition, including differences in threat perception between the United States and South Korea. But they also believed that multilateral dialogue still offers the best possibility for resolving the DPRK nuclear issue through peaceful means. Participants argued that in the wake of the nuclear test, pressure and use of force should be discounted as viable options and "rollback" through negotiations should be pursued. Such an approach necessitates clearer articulation of North Korea's options, a new consensus on mutual priorities, hard work on sequencing, and a more developed vision for alternative policies should diplomacy fail.

The U.S.-ROK alliance has entered a new era characterized by new American security imperatives, such as nonproliferation and counterterrorism, as well as a new Korean policy of engagement toward the DPRK. These factors, coupled with domestic political challenges and an evolving regional security environment, call for serious, strategic discussions on the state of the alliance. Though the U.S. and the ROK have exhibited diverging threat perceptions of North Korea the - core of the strategic rationale for the alliance - the instructive precedent set by NATO demonstrates that alliances can survive redefinition of the primary security threat, though not the absence of a common threat.

Participants discussed the prospects for greater regional cooperation in Northeast Asia, including the possibility of converting the six-party talks into a new institutional mechanism for multilateral security cooperation. However, there are serious obstacles to deeper integration in the region, not least unresolved historical issues that still elicit passionate responses. But if understandings on these issues can be reached, a regional security organization could address critical traditional and non-traditional security issues and mitigate uncertainty about China's rise.

The full text of the report can be found at The First Korea-West Coast Strategic Forum.

The alliance between the Republic of Korea and the United States has been facing new pressures in recent months. Leaders in Washington and Seoul are visibly out of synch in their response to the escalatory actions of North Korea, beginning with the July 4 missile tests and leading to the October 9 nuclear explosion. South Korean leaders seem more concerned with the danger that Washington may instigate conflict than they are with North Korea's profoundly provocative acts. American officials increasingly see Seoul as irrelevant to any possible solution to the problem. Officials on both sides valiantly try to find areas of agreement and to paper over differences. If attempts to restart the six-party talks on North Korea falter again, it is likely this divide will resurface.

There is a tendency on both sides of the Pacific to overdraw a portrait of an alliance on the verge of collapse. Crises in the U.S.-ROK alliance are hardly new. As I have written elsewhere, there never was a "golden age" in our alliance that was free from tension. Korean discomfort with an alliance founded on dependency and American unease with Korean nationalism has been a constant since the early days of this relationship. Clashes over how to respond to North Korea have been a staple of the alliance since its earliest days.

Korean-American relations today are much deeper than at the inception of this alliance. Our interests are intertwined on many fronts, not least as major players in the global economic and trading system. We share fundamental values as democratic societies, built on the rule of law and the free flow of ideas. There is a large, and growing, contact between our two peoples, from trade and tourism to immigration.

The current situation is worrisome however because it threatens the security system that lies at the foundation of the alliance. Though our interests are now far broader, the U.S.-ROK alliance remains military in nature. The founding document of this alliance was the

Mutual Defense Treaty signed on October 1, 1953, following the conclusion of the armistice pact to halt the Korean War. That treaty has been significantly modified only once - 28 years ago in response to American plans to withdraw its ground forces from Korea - to create the Korea-U.S. Combined Forces Command (CFC).

The two militaries have a vital legacy of decades of combined command, training and war planning. American military forces in significant numbers have remained in place to help defend South Korea from potential aggression from the North. South Korean troops have deployed abroad numerous times in support of American foreign policy goals, including currently in Iraq and Afghanistan.

This foundation of security is not only essential to this alliance but is the very definition of the nature of alliances in general, as distinct from other forms of cooperation and partnership in international relations.

"Alliances are binding, durable security commitments between two or more nations," Dr. Elizabeth Sherwood-Randall, a Stanford scholar and former Clinton administration senior defense official, wrote recently. "The critical ingredients of a meaningful alliance are the shared recognition of common threats and a pledge to take action to counter them. To forge agreement, an alliance requires ongoing policy consultations that continually set expectations for allied behavior."

Alliances can survive a redefinition of the common threat that faces them but not the absence of a threat. Nor can alliances endure if there is not a clear sense of the mutual obligations the partners have to each other, from mutual defense to joint actions against a perceived danger. "At a minimum," Sherwood-Randall says, "allies are expected to take into consideration the perspectives and interests of their partners as they make foreign and defense policy choices."

By this definition, the U.S.-ROK alliance is in need of a profound re-examination.

The 'shared recognition' of a common threat from North Korea that was at the core of the alliance is badly tattered. As a consequence, there is no real agreement on what actions are needed to counter that threat.

There is a troubling lack of will on both sides to engage in policy consultations that involve an understanding of the interests and views of both sides, much less setting clear expectations for allied behavior. Major decisions such as the phasing out of the CFC have been made without adequate discussion.

Americans and Koreans need, in effect, to re-imagine our alliance. We should do so with the understanding that there is still substantial popular support for this alliance, despite conventional wisdom to the contrary. The problems of alliance support may lie more in policy-making elites in both countries than in the general public. That suggests that a concerted effort to reinvigorate the alliance will find public backing.

The results of the Chicago Council on Global Affairs 2006 multinational survey of public opinion show ongoing strong support for the American military presence in South Korea. Some 62 percent of Koreans believe U.S. troop levels are either about right or too few; some 52 percent of Americans share that view. A slightly larger percentage of Americans - 42 percent compared to 36 percent of Koreans - think there are too many U.S. troops. Along the same vein, 65 percent of Americans and 84 percent of Koreans favor the U.S. providing military forces, together with other countries, in a United Nations-sponsored effort to turn back a North Korean attack.

The crack in the alliance comes over the perception of threat from North Korea.

While some 79 percent of Koreans feel at least "a bit" threatened by the possibility of North Korea becoming a nuclear power, only 30 percent say they are "very" threatened. Fewer Koreans feel the peninsula will be a source of conflict than the number of Americans. More significantly, nuclear proliferation is viewed as a critical threat by 69 percent of Americans, compared to only half of Koreans (interestingly, Chinese are even less concerned about this danger).

The opinion poll was conducted before the nuclear test so it is difficult to judge the impact of that event. These survey results do clearly indicate however that while the security alliance still has support, there is an urgent need for deep discussion, at all levels, about the nature of the threat.

The crisis that faced the NATO alliance in the wake of the end of the Cold War has some instructive value for Koreans and Americans today. At the beginning of 1990, I was sent by my newspaper, the Christian Science Monitor, from Tokyo, where I had been covering Japan and Korea since the mid-1980s, to Moscow. The Berlin Wall had fallen a few months earlier and the prospect of the end of a half-century of Cold War in Europe was in the air. However, I dont believe anyone, certainly not myself, anticipated the astounding pace or scale of change that took place within just two years.

Within less than a year, in October of 1990, West and East Germany were reunited.

The once-mighty Soviet empire in Eastern Europe disintegrated almost overnight. By July of 1991, the Warsaw Pact had come to an end. Perhaps most astounding of all - not least to officials of the administration of George H.W. Bush - the Soviet Union fell abruptly apart in December 1991.

These tectonic events triggered a debate about the future of the NATO alliance that had provided security to Europe since it was founded in April of 1949. Soviet leader Mikhail Gorbachev somewhat famously - and perhaps apocryphally - anticipated this debate. "We are going to do something terrible to you," he is said to have told Ronald Reagan. "We are going to deprive you of an enemy."

In those early days, the very continued existence of NATO was under active discussion. The Soviet leadership called for the creation of entirely new "pan-European" security structures that would replace both NATO and the Warsaw Pact. Some in Europe favored the European Union as a new vehicle for both economic integration of the former

Soviet empire into Europe, along with creating new European security forces that would supplant NATO's integrated command.

A more cautionary view argued for retaining NATO without change as a hedge against the revival of Russia as a military threat or the failure of democratic and market transformation in the former Soviet Union. American policymakers opted instead for the ambitious aim of expanding NATO membership to absorb, step by step, the former Soviet empire, including the newly freed western republics of the Soviet Union.

Along with expansion, the United States pushed NATO to redefine the "enemy." Americans argued that new threats to stability and security from ethnic conflict - and international terrorism - compelled NATO to "go out of area or out of business." NATO did so first in the Balkans, in Bosnia and Kosovo, though reluctantly. The alliance has moved even farther beyond Europe to Afghanistan, where NATO commands the international security forces. This draws upon the invaluable investment made in joint military command and operations that are the foundation of the alliance.

Certainly NATO's transformation is far from complete. As was evident at the most recent NATO summit in Riga, considerable differences of opinion remain between many European states and the United States over the mission of NATO. Europeans tend to still see NATO as an essentially defensive alliance, protecting the "euro-Atlantic" region against outside aggression, with an unspoken role as a hedge against uncertainties in Russia. They are resistant to continued American pressure for expansion - including a new U.S. proposal to move toward global partnership with countries such as Japan, South Korea and Australia.

But the reinvention of NATO after the Cold War provides some evidence that even when the nature of the threat has changed, security alliances can preserve a sense of common purpose.

A re-imagined U.S.-ROK alliance could draw from the NATO experience by including the following elements:

HEDGE - The alliance remains crucial as a 'hedge' against North Korean aggression, even if the dangers of an attack are considered significantly reduced. If North Korea retains its nuclear capability, that hedge will need to expand to include a shared doctrine of containment and deterrence, including making clear that the U.S. will retaliate against use of nuclear weapons, no matter where it takes place. Strategically the alliance is also a 'hedge' against Chinese ambitions to dominate East Asia and a guarantor of the existing balance of power;

EXPANSION - The alliance can reassert its vitality as the basis, along with the

U.S.-Japan security alliance, of an expanded multilateral security structure for

Northeast Asia;

NEW MISSIONS - The alliance should take on new missions, most importantly to participate in military and non-military counter-proliferation operations;

OUT OF AREA - A re-imagined alliance might formalize an "out of area" role, elevating the deployments of peacekeeping and other forces to Iraq and Afghanistan into more systematic joint global operations between the two militaries. In this regard, the participation of South Korea in a program of global partnership with NATO, most importantly in the area of joint training, merits serious discussion.

There is another alternative: South Korea and the United States can chose to bring their alliance to a close. If we cannot agree on the common threats that face us, this alliance cannot endure. What we should not do is to allow the alliance to drift from inattention into a deeper crisis that would only benefit our adversaries.

To read the seismic signal sent from an abandoned coal mine in the mountains of North Korea's coast, you must first recognize that it represents four major failures, two grave dangers, and one big opportunity.

The apparent explosion of a nuclear device, coming after two decades of trying to stop North Korea from achieving this goal, is a manifest failure of policy on four fronts -- a failure of U.S. nuclear non-proliferation policy, a failure of international diplomacy, a failure of Chinese leadership and a failure of South Korea's strategy of engaging the North.

Having failed so completely, the world now faces two grave dangers. The first is the very real threat of war on the Korean Peninsula, triggered by a series of escalatory actions in the wake of the bomb test. The second is the danger that North Korea will proliferate its nuclear technology, materials or know-how to others -- not the least to another nuclear hopeful, Iran.

But there remains a lone and tenuous opportunity. Having removed all ambiguity about its nuclear ambitions, North Korea may finally have created a common sense of threat that will galvanize the kind of concerted international action that so far has been absent.

THE FOUR FAILURES

Non-proliferation failure

The United States has spent two decades trying to stop North Korea from going nuclear, a turbulent period of crisis and negotiation that even went to the brink of war. At least three administrations confronted this problem and none, certainly not the Bush administration, can escape blame.

North Korea agreed to sign the Nuclear Non-Proliferation Treaty (NPT) in 1985, but it stalled before signing an agreement with the International Atomic Energy Agency (IAEA) in 1992 to place its nuclear facilities under international safeguards and inspections. During that time the North Koreans reprocessed some spent fuel from their reactor into plutonium - an amount that American intelligence believes was enough for building one or two warheads.

North Korea's resistance to full inspections, while it kept pulling spent fuel rods out of its reactor, provoked a crisis in 1994 and led the Clinton administration to ready military forces to strike the North's nuclear facilities. In a last-minute deal, North Korea froze its reactor and reprocessing facilities, effectively halting plutonium production under IAEA supervision. In exchange, the United States, Japan, South Korea and others agreed to construct two light-water reactors for North Korea and to supply fuel oil until the reactors came online.

The deal was troubled from the start. Neither party was satisfied with the compromise or the way it was to be implemented. By the late 1990s, the North had begun a secret effort to acquire uranium-enrichment technology from Pakistan and, in 1998, tested a long-range ballistic missile. Despite this, the plutonium freeze remained in place. But it did not survive the Bush administration.

The Bush administration came into office challenging the value of the agreement and froze contacts with the North. After receiving intelligence showing moves to build enrichment facilities, it confronted North Korean officials at an acrimonious meeting in Pyongyang in October 2002.

The United States halted fuel shipments a month later, and, in early 2003, the North Koreans expelled IAEA inspectors and withdrew from the Non-Proliferation Treaty. They proceeded to reprocess the fuel rods they had stored for a decade, producing enough plutonium, intelligence estimates say, for four to six nuclear warheads. In February 2005, the North Koreans announced they had manufactured nuclear weapons. Last week, they apparently made good on that declaration.

Blame aside, North Korea's emergence as the world's ninth nuclear power may be the most serious failure in non-proliferation history. Unlike India and Pakistan, which remained outside the system of international treaties, North Korea acted in defiance of those controls. Who might be next?

Diplomatic failure

Unlike Iraq, the attempt to stop North Korea's nuclear program has relied on the tools of diplomacy, accompanied by economic incentives and coercive sanctions.

But serious questions have been raised from the start about the sincerity and methods of the diplomatic efforts, particularly on the part of the United States and North Korea. The Bush administration has insisted -- and the president continues to make this argument -- that direct talks with North Korea do not work. Pyongyang has tried to frame everything as an issue with Washington, undermining talks that involved others, including South Korea.

Bush's stance lends credibility to those who charge the administration seeks "regime change," not a compromise that it believes will lend legitimacy to Kim Jong Il. The North Koreans now appear to have used the talks to buy time and build bombs.

Diplomacy has, at American insistence, consisted of six-party talks, held under Chinese auspices and including both Koreas, Japan and Russia. In truth, little real negotiating went on at these gatherings, at least until the last full round of talks in September 2005. In contrast to the thousands of hours of negotiations between Americans and North Koreans that led to the 1994 deal, there have been only tens of hours of actual give and take.

It is intriguing that the September agreement on a statement of principles for denuclearization came only after the State Department's chief negotiator was finally allowed to talk to his North Korean counterpart at length. Even then, their agreement evaporated almost immediately as they dueled publicly over the deal's meaning. American financial sanctions against North Korean currency counterfeiting further clouded the atmosphere, and direct contacts ground to a halt.

China's failure

The North Korean nuclear crisis is also a failure of China's bid for regional, if not global leadership. North Korea is an ally of China, a relationship that goes back more than half a century to the Korean War, when Chinese "volunteers" poured across the border to prevent an American victory. Their relationship has become more difficult since China embarked on market reforms while North Korea clung to its peculiar brand of Stalinism.

China has been torn between its loyalty to Pyongyang, its desire to maintain a stable balance of power in the region and its fear that the North's nuclear ambitions could provoke conflict on its borders. By becoming host for the six-party talks, Beijing stepped into an unusual leadership role.

The Bush administration was eager to move the burden of the North Korean problem onto the Chinese. Some administration hard-liners argued that China had the power to trigger the collapse of Kim Jung Il's regime by cutting off energy and food supplies.

Time and again, Beijing dragged the North Koreans back to the negotiating table, while also pushing Washington to engage Pyongyang in the talks. But Chinese irritation over American inflexibility has now been trumped by North Korea's defiance. Chinese policy-makers now wonder how they can punish the North without creating chaos, or war.

Failure of engagement

The final failure lies on the doorstep of South Korea's 10-year-long policy of engagement. The "sunshine policy" asserted that the North could be induced to give up its nuclear option by opening up the isolated communist state and promoting the forces of Chinese-style reform.

After a historic summit meeting in 2000, South Korean aid and trade, even tourists, flowed into the North. South Koreans lost their fear of a former foe, seeing it more as an impoverished lost brother than a mortal threat. Tensions with their American allies rose because of a gap in the North's perceived threat. The United States wondered why its troops should continue to defend South Korea.

Now South Koreans must confront the possibility that the North may have used engagement only to buy time.

THE TWO DANGERS

Threat of war

With eyes on Iraq and the Middle East, the Korean Peninsula has been far from the center of American attention. American forces based in South Korea and Japan have been dispatched to Iraq.

Yet the demilitarized zone that separates the two Koreas remains the most militarized frontier on the planet, with hundreds of thousands of well-armed soldiers poised against each other. Clashes along that frontier used to be commonplace and there are signs of a renewal of tensions. The danger of unintended escalation cannot be dismissed.

What might happen if a U.S. naval vessel, moving to inspect a North Korean freighter - as the U.N. resolution may authorize - is fired on or even captured, as the USS Pueblo was in 1968? It is a frightening scenario already worrying some at the Pentagon and the State Department.

Risk of proliferation

More than anything else, American policy-makers fear that North Korea, emboldened by its nuclear success and perhaps desperate for funds amid economic sanctions, might sell its nuclear expertise to Iran and others, including terrorist groups.

For Pyongyang, an alliance with Iran is a logical response to American and global pressure. The North Koreans have sold ballistic missiles to Tehran since the 1980s and rumors of nuclear cooperation persist.

An American effort to interdict the movement of ships and planes to Iran -- with possible U.N. backing - is probable. But the most likely transit is across the long and loosely controlled land border with China. The amount of plutonium needed to make a warhead is the size of a grapefruit and hard to detect - creating yet another nightmare scenario.

THE OPPORTUNITY

In this otherwise bleak landscape, there is an opportunity. For the first time, there is a chance of a consensus among the key players -- China, Japan, South Korea, Russia and the United States. The passage of a U.N. resolution is a small step in that direction. But the real test will come next, as the nations must cooperate to put pressure on North Korea, while coolly navigating the perils of war and making sure to leave open a diplomatic exit.

There is a slim chance of such concerted action, and a limited window for achieving it. Not everyone sees the dangers the same way. Signs of rethinking errors of the past are no more evident in Beijing and Seoul than they are in Washington or Tokyo. Ultimately, however, if they are to seize this moment of opportunity, all parties must face up to the fact that the policies of the past have failed.
