Pre-emption used to be the watchword of Bush foreign policy. The world's sole superpower would not hesitate to wield force against an imminent threat to its security. The old doctrines of the Cold War era -- of containment and deterrence of a potential enemy -- were disdained as weakness.

Now, facing the most serious national security challenge since the end of the Cold War -- the nuclear weapons programs of Iran and North Korea -- the administration is reaching back to those oldies but goodies.

The determination of Iran and North Korea to develop nuclear weapons has so far been largely unchecked by this administration. The North Koreans, since breaking out of the freeze agreed to during the Clinton administration, have been steadily producing plutonium, and presumably warheads. The Iranians, after the election of hard-line President Mahmoud Ahmadinejad, reversed their deal to suspend uranium-enrichment activities, the crucial step toward nuclear weapons.

Diplomatic negotiations in both cases have produced little movement. But a military strike on their nuclear facilities is almost inconceivable. The danger of potentially horrendous retaliation and the sapping of American will and resources in Iraq have almost killed that option.

"As shaky as a policy of containment is, it is certainly preferable to confrontation, 'rollback,' or 'regime change' through military force,'' wrote conservative national security expert Thomas Donnelly in a recent analysis. "Containment is, in fact, regime change by tolerable means, and the solution to the problems of Iran and North Korea lie in an indirect approach.''

While we try to contain a nuclear Iran and North Korea, suggested Donnelly, we should surround Iran with movements for democratic change in Iraq and Afghanistan. North Korea, he believes, will be changed through Chinese influence.

Donnelly cautions that there may be circumstances when containment proves even more risky than intervention -- say if Iran tries to slip nuclear materials to Islamist terrorists. Iran is less stable than the Soviet Union, though it is worth remembering that the first 15 years of the Cold War brought us to the brink of nuclear war once and close to it several times.

For the administration, this is a stealth policy shift. That is no surprise. It flows directly from the mess in Iraq, a mistake the administration can never really acknowledge.

For those who once touted American global domination, it is still hard to face the reality that containment is impossible without allies and partners. By ourselves, we cannot press those regimes by cutting off their access to investment and advanced technology.

The administration is rightly moving to take Iran to the United Nations Security Council to seek a mandate to enforce the demands of the International Atomic Energy Agency. North Korea is undoubtedly watching this carefully.

China and Russia, who have veto power in the Security Council, are reluctantly going along. But they still resist any move to impose economic sanctions against Iran. Nor are the Europeans, Japanese and others who depend on oil and gas from Iran eager to halt their investment and trade.

Similarly in the case of North Korea, the Chinese and South Koreans are not prepared to cut the flow of economic aid and investment into the otherwise isolated North Korean state. This is less a case of economic interests than a fear that sanctions will escalate to greater confrontation, even war.

"The strategic challenge the Bush administration faced was to convince the rest of the world that Iran is more dangerous than the United States,'' says nuclear proliferation expert George Perkovich. "They finally did it -- and it took Ahmadinejad to do it,'' referring to the inflammatory rhetoric, including threats to "wipe Israel off the map,'' issued by the Iranian leader.

The administration made some headway down the same path with North Korea by engaging in direct talks with that regime this past fall, dispelling the image that the United States was unwilling to negotiate. But that progress has been undermined recently because hard-liners inside the Bush administration pulled the plug on such talks.

Managing an effective containment partnership will be a huge challenge. And there is still tremendous resistance inside the administration to engaging and negotiating -- and compromising -- with the enemy. But that was always a part of making containment succeed, even at the height of the Cold War.

Containment is no silver bullet. It is merely, as Donnelly puts it, "the least bad alternative, but not by a lot, and not under all circumstances.'' And right now, it is the only game in town.

Despite its attempt to soften criticism of the war, there is no evidence the Bush administration is capable of self-correction.

That came home to me the other day while listening to a senior administration official deliver an off-the-record tour d'horizon of American foreign policy. He is among the best minds in this administration, counted among the ranks of the realists, rather than the neoconservatives.

The United States stands alone as the most powerful nation in the world, the official began. In no previous moment of human history has a single state enjoyed such a dominant position.

When it comes to managing its relations with other would-be powers -- Europe, China, Japan and India -- the United States has done "extraordinarily well,'' he said.

The tensions generated by the war in Iraq have eased, the senior foreign policy official confidently asserted. The Europeans are content to gaze intently inward, he observed, while America strides the globe.

Japan is embracing the United States in a very close relationship that shows no sign of unraveling. Meanwhile the Bush administration has forged a growing partnership with India.

When it comes to China, the administration has chosen the path of accommodation and integration rather than containment of the rising power. He expressed confidence that American power and the prospect of democracy in China will secure the peace.

The only remaining challenge for the United States is to combat the threat of a radical Islamist movement that seeks to acquire weapons of mass destruction. For that, there is the promotion of democracy and American values around the world. After all, the official said with not even a nod to humility, "the U.S. is the most successful country that has ever existed.''

A year or two ago, the American people embraced this vision of a confident colossus, a Gulliver among the Lilliputians. That was before they watched the giant tied down in its attempt to export those American values by force of arms in Iraq.

The arrogance of this administration would be barely tolerable if it were not paired with a stunning incompetence, on display from Kabul to Katrina. That deadly combination has weakened American strength in the world. It has emboldened far more serious challengers in Iran and North Korea, who see the United States as too bogged down in Iraq to credibly threaten them with the use of force.

The war rated barely a mention in the sweeping view offered by the senior administration official, except indirectly. He offered a realist defense of the administration's democracy crusade.

World War II was fought with democratic goals, the official pointed out. And the Cold War -- the model for the current struggle against Islamic extremism -- was not just about balancing the power of the Soviet Union. The wars in Korea and Vietnam were really about determining which system those countries chose, he argued.

Those are curious examples to cite as a defense of the decision to go to war in Iraq. The United States shored up authoritarian regimes in Korea and Vietnam to counter the communist threat. Vietnam was a strategic mistake that took decades to overcome. And democracy came to Korea more than 35 years later, after a long period of economic development.

President Bush cited the democratic transformation of Korea -- along with Taiwan and Japan -- in a recent speech during his trip to Asia. But these are examples of the "conventional story in which you become rich and then you become democrats,'' as the senior official put it so well.

The administration proposes however to skip this long, but necessary, path to democratic capitalism when it comes to the Middle East. The policies of security and stability have failed there and a quicker route to democratic change is called for. But there is no historical evidence to suggest that this is any more than another manifestation of a blind belief in American power.

Democratic values have always been essential to American foreign policy. In practice, however, American administrations have often made painful choices between stability and the promotion of democracy. We saw that too often during the Cold War -- in Budapest in 1956, Prague in 1968 or Tibet in 1959.

The administration might do well to recall the words of candidate Bush, uttered Oct. 11, 2000.

"It really depends on how our nation conducts itself in foreign policy. If we're an arrogant nation they'll resent us,'' Bush said. "But if we are a humble nation, they'll respect us.''

What is the state of China-Taiwan relations?

President George Bush fanned the flames of the longstanding conflict between China and Taiwan during his November 16 speech in Kyoto, at the start of a week-long state visit to Asia. In urging China to expand openness and allow its people more freedoms, the president used Taiwan as a model, saying Taiwan had brought prosperity to its people by embracing freedom and creating a democratic Chinese society. China rejected Bush's comments. "Taiwan is an inseparable part ofChina, and China does not brook any interference in its internal affairs," Foreign Minister Li Zhaoxing told reporters at the Asia-Pacific Economic Cooperation (APEC) summit in South Korea. Bush meets Chinese President Hu Jintao and other Asian leaders at the summit November 19.

What is the history of the conflict?

Taiwan, an island of 23 million off China's southern coast, was occupied by Japan for fifty years, from 1895 to 1945. In 1949, after Chiang Kai-shek's Nationalist Party lost its power struggle with the Communist Party in China, Chiang and his followers fled to Taiwan. Their Kuomintang (KMT) government-in-exile in Taipei defined itself as the alternative to Communist rule and hoped one day to return to power in Beijing. The KMT governed Taiwan from 1949 to 2000; its often harsh rule included discriminatory laws against ethnic Taiwanese and nearly forty years of martial law, which was finally lifted in 1987. The KMT has historically seen Taiwan as a part of "one China" that would eventually be reunited under Nationalist rule.

Taiwan's current ruling party, the predominantly ethnic Taiwanese Democratic Progressive Party (DPP) was founded in 1986 to counter the KMT, and only became legal in 1989 after a longtime ban on opposition parties was dropped. Taiwanese President Chen Shui-Bian is a member of the DPP, which envisions Taiwan as an independent nation, separate from China. In 2000, Chen was the first DPP candidate to be elected president. Taiwanese sovereignty is the first and most prominent issue on the party's platform. This position has put the DPP severely at odds with China's leadership, which views Taiwan as a renegade province that will one day be reunited with Communist China--by force, if necessary.

What is the U.S. position?

The United States officially recognizes only one China -- including Taiwan -- and urges a peaceful resolution to the Taiwan question. However, Washington is also bound by the 1979 Taiwan Relations Act to aid in Taiwan 's defense, including selling the island the weapons it needs to defend itself against China. Experts say the United States is walking a fine line between China 's growing influence and the historical U.S. relationship with Taiwan. "Bush had to stand up for freedom and democracy and all the other values he constantly talks about, without picking a fight with China that nobody really wants," says David Kang, an Asia expert and visiting professor at Stanford University's Shorenstein APARC. Bush stressed in his speech that "there should be no unilateral attempts to change the status quo by either side."

What is the impetus behind independence for Taiwan?

After the long KMT reign, many Taiwanese are now pushing for self-determination. Independence advocates say Taiwan is a free and democratic nation with multiparty elections and a very successful economy, with a gross national product (GNP) of $328 billion in 2004, of which $174 billion was due to exports including electronics, computer parts, textiles, metals, plastic, and rubber. They say the Taiwan people should have the right to decide for themselves if they want to join China or become an independent nation. Since Chen was elected to his first term in 2000, he has steadily pushed the idea of Taiwanese independence. He provoked Beijing August 3 by supporting the idea of a referendum to ask Taiwanese citizens if the island should declare formal independence from China. China is very hostile to such talk: On August 7, the official China Daily newspaper quoted a Chinese military official saying, "Taiwan choosing independence is tantamount to choosing war."

What has China been doing?

Making both incendiary statements and conciliatory moves. In July, General Zhu Chenghu, the dean of China's National Defense University, warned that China would attack the United States with nuclear weapons if it intervened in a military dispute over Taiwan. Although he later claimed the comments were his own and did not reflect the views of the state, Zhu's words generated international concern. However, China's actions toward some Taiwanese officials have been friendlier. James Soong, head of the Taiwanese opposition party People First, has visited China several times in the last year at the invitation of Beijing. Experts say Beijing is reaching out to opposition leaders in Taiwan in an attempt to sidestep the DPP and build new bases of support on the island. Soong is taking advantage of the opening to play for domestic political support and attempt to show up the DPP, they say. His actions infuriate the ruling party in Taiwan because, despite his unofficial status, Soong is building friendly relations with China in direct contrast to DPP policy.

What are the next steps?

Bush alluded to peace talks in his November 16 speech, but experts say such talks between China and Taiwan are unlikely in the near future. "There are elements moving towards peace talks, and other elements, especially in Taiwan, that are pushing toward independence and want to stick China in the eye," David Kang says. But "it's hard to say what Taiwan wants," he adds, noting the Taiwan electorate is almost evenly split between those who favor independence and those who want to improve relations with Beijing for historical, cultural, and especially economic reasons. David Kang says that, in the last several years, as many as one million Taiwanese have moved to China to do business.

What are Taiwan's security concerns?

China, located just 100 miles away across the Taiwan Strait, has hundreds of ballistic missiles aimed at Taiwan, and is targeting much of its recent militarization campaign specifically at the island, including building amphibious tanks that can be used to storm Taiwan's shores. China's military buildup has put Taiwan at a strategic disadvantage: Taiwan's military spending has dropped 25 percent over the last five years, to only 2.4 percent of gross domestic product (GDP). The United States has been pressuring the island to buy a specially designed $18 billion package of U.S. arms to improve its military capabilities. But some Taiwanese politicians are reluctant to devote resources to military buildup given the presumed U.S. protection, and opposition leaders have blocked the sale over what experts call domestic political squabbling. But, David Kang points out, a military invasion of Taiwan by China is highly improbable. "That's the least likely scenario," he says. "You can have a military dispute that's far short of all-out war."

On the surface, President Bush's week-long swing through Northeast Asia has been a strong contrast with his recent stormy (and, some say, stumbling) excursion into Latin America.

There was little sign of overt anti-Americanism. And no Asian leader will openly oppose American leadership in the flamboyant manner of Venezuela's Hugo Chavez. Even prickly China swallowed President Bush's barbs about lack of democratic freedom in China, quietly acknowledging the two powers' differences. In contrast to the meeting of leaders from the Americas, the annual summit of the Asia Pacific Economic Cooperation (APEC) forum in Korea will embrace the principles of free trade.

Beneath the polite appearance, however, there is no less a challenge to American leadership in Asia. While Washington fiddled, a powerful momentum has been building up in Asia toward the formation of an East Asian Free Trade Area or, more ambitiously, an East Asian Community, modeled on the European community. Led by China, the East Asian grouping pointedly excludes the United States.

The APEC agenda focuses on an initiative to counter the spread of avian flu and to offer a common push at the WTO meeting in Hong Kong next month to revive the Doha Round of global trade talks. The Bush administration has its own agenda for the APEC meeting: to reposition itself as a leader of economic growth and integration in the region. For this, APEC has the virtue of being a more open organization than those behind the disappointment at the American summit. Its 21 members span the Pacific Rim, bringing together nations from Chile and Mexico to Russia, China and Southeast Asia. But this attention to APEC may be a case of too little, too late. The momentum to give the amorphous APEC an ongoing institutional role, beyond its annual summit meetings, has slowed in recent years. Its pledges for mutual tariff reduction exist almost entirely on paper.

Until this year, the Bush administration barely addressed regional economic issues at APEC. It preferred to use the meetings to promote a post-9/11 security agenda of anti-terrorism. U.S. trade policy has focused more on reaching free trade agreements with a few selected "friends" in that war, such as Singapore and Australia.

Meanwhile a Chinese-sponsored move to hold an East Asian summit offers the most visible expression of a trend of declining American influence in Asia. That meeting will take place in Malaysia in mid-December. The gathering groups the 10-member Association of Southeast Asian Nations, Japan, China, South Korea, India, Australia and New Zealand. Pointedly not invited is the United States.

This meeting is an outgrowth of the ASEAN Plus Three (APT) process - an annual dialogue of ASEAN with China, South Korea and Japan that began in December 1997 in the midst of the Asian financial crisis. The APT has grown into an elaborate mechanism for cooperation in a range of areas from finance and agriculture to information technology. This reflects an underlying economic reality - the growth of regional and bilateral trade agreements and the rapid rise of intra-Asian trade.

Until fairly recently, foreign trade in East Asia was dominated by trans-Pacific trade with the United States. But the share of Asian exports headed to the U.S. has dropped dramatically, while those destined for other Asian nations has risen. In the two decades from 1981 to 2001, according to economist Edward Lincoln, the share of intra-regional exports has risen from 32 percent to 40 percent, and intra-regional imports from 32 percent to 50 percent.

Much of the growth of regional integration is being driven by China, which is generating enormous demand for imports of raw materials as well as for semi-finished goods that are assembled for export. China has not been hesitant to use this role to expand its influence in the region. It has embraced the APT as a road towards creation of an East Asian community. At the ASEAN summit last year, Chinese Premier Wen Jiabao declared that such a community was a "long-term strategic choice in the interests of China's development." China has also outmatched the U.S. in negotiating free trade agreements, both bilateral and regional. The most impressive is an FTA deal between China and ASEAN set to take effect in 2010. Beijing even dreams of an Asian currency, based on the Chinese yuan, to rival the dollar and the euro.

China is not the first nation to try for such East Asian economic unity. Back in the days when Japan was riding high as an economic superpower, it too talked of leading an East Asian bloc, based on a yen currency zone. As late as 1997, in response to the Asian financial crisis, Japan proposed the creation of an Asian Monetary Fund, a kind of alternate regional financial system. More recently, both South Korea and Japan offered their own visions of an East Asian community in 2001. And both countries tried to match China in the APT by offering to form free trade agreements with ASEAN.

Japan, however, was never as successful as China is likely to be. "It would seem that Japan is a natural counterweight to China, but Tokyo is generally perceived as reactive and incapable of outflanking Beijing," Brad Glosserman, director of research at the Pacific Forum of CSIS, wrote recently. "Its economic dynamism is no match for that of China."

The United States has never been friendly toward efforts to create an East Asian economic bloc, viewing them as chipping away at the global trading system and rivaling American leadership. But Asia is arguably only following in American footsteps -- witness the NAFTA deal with Canada and Mexico and the more recent trade pact with Central America.

Many American policymakers believe these developments are partly a product of the failure of the Bush administration to articulate - much less pursue - a strategy to engage East Asia.

"The United States has greater strategic interests in Asia now than it did in Europe before World War I or World War II,'' argued a recent report of the Grand Strategic Choices Working Group, co-chaired by John Hopkin's University's Francis Fukuyama and Princeton's G. John Ikenberry. "Thus," the report continued, "it is unfortunate that part of the problem, in East Asia in particular, is that America's relative lack of interest in tending to the region has caused some allies of the U.S. to doubt our resolve and question the value of resisting unfavorable developments alone."

The report echoes other policymakers in suggesting the U.S. form its own East Asian economic zone with Japan, South Korea and Australia."That's a non-starter,'' says Professor Vinod Aggarwal, director of Berkeley's APEC study center. "Nobody wants to be cut out of the China market."

Privately, Bush administration officials downplay the importance of the East Asian summit in December, pointing to the lack of any concrete agenda. The addition of India, Australia and New Zealand to the invitation list, along with Japan, should effectively counter any Chinese initiative, they believe.

But those countries also fear being left out of whatever may emerge from this process. They cannot afford to be left on the outside, looking in.

Ultimately, neither can the United States. The President's trip is a belated recognition of that fact. But to be more than a momentary gesture, the United States must give East Asia the consistent attention it deserves.
