Effectiveness of the balloon campaign is questioned

In an interview with Ars Technica about the visit to the Bay area of North Korean defectors, KSP associate director David Straub criticized their launching of propaganda-carrying balloons into North Korea as irresponsible in light of North Korean threats to retaliate by again attacking South Korea militarily. Although not included in the published interview, Straub prefaced his comments by noting that he "strongly agree[d] on the need to provide the North Korean people with as much information as possible about the outside world and their situation in it," but questioned the effectiveness of the balloon campaign compared to other, less provocative means.
