防扩散

After Cold War, the status of Foreign Aid declined in the U.S national stratagem and its fund has been decreased to a level of less than a third of that in peak. After 9.11 Events, the global stratagem of the U.S changed in a large degree and transferred its core to Antiterrorism and anti-diffusion of weapons of mass destruction. At that time, the U.S drew its attention back to the Foreign Aid, such as Political Aid, Military Aid and Economic Aid, and took it as a powerful tool in global antiterrorist stratagem.

冷战结束后，对外援助在美国国家战略中的地位有所下降，美国对外援助的拨款一度降到不到其高峰期的三分之一的水平。9.11恐怖袭击后，美国全球战略发生重大转变，反恐和防止大规范杀伤性武器的扩散以保障其国家安全成为美国的核心战略，美国在全球展开了声势浩大的反恐战争，这时候，小布什政府开始重新重视对外援助，把对外援助当作其全球防恐战略的一个有力工具，政治、军事援助和基于政治、军事目的的经济援助在小布什么政府里又开始大行其道。
