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.
