Since the Bush administration took office, and especially since excerpts of the Nuclear Posture Review were released, there have appeared in America some heated arguments about the Bush administration's changes to the Clinton administration's nuclear strategy, what consequences these changes would produce, and what influences they would exert on international and regional security. Different people have different views. The purpose of this working paper is to find solutions to these key issues. The effects of the Bush administration's nuclear strategy on China's security are also discussed.

The main viewpoint of the working paper is that the Bush administration has made the most fundamental adjustments to America's nuclear strategy since the end of the Cold War. These adjustments greatly modify U.S. nuclear deterrent strategy, the country's policy on using nuclear weapons, the triad of deterrent forces structure, and nuclear arms control policy. The new nuclear strategy would upset a balance of forces and stability regionally and around the globe. Moreover, the United States is shifting the focus of military strategy from Europe to Asia. This would exert significant influences on Asian-Pacific regional security and China's security.
