Abstract. During the last twenty years Washington has used the “counter-proliferation strategy” in Korean Peninsula. The Americans demanded that North Korea eliminate its nuclear arsenals and plutonium production facilities under the watchful eye of the “five powers’ commission” or the IAEA. Pyongyang's recent military provocation may now raise the specter of the United States or even South Korea delivering non-nuclear strikes against its nuclear facilities. That would give the USA an opportunity to raise the question of whether certain regimes should be allowed to acquire nuclear weapons or even to develop nuclear fuel cycle capacity. The last crises demonstrated that under certain circumstances North Korea could also initiate a military conflict in East Asia.
