The United States military has been building up forces on the U.S. territory of Guam to increase deterrence and power projection for possible responses to crises and disasters, counter-terrorism, and contingencies in support of South Korea, Japan, the Philippines, Taiwan, or elsewhere in Asia.

This report describes in brief detail the various cooperative efforts, including financial efforts, undertaken by the U.S. and the above nations.

This report focuses on the potential implications of China's naval modernization for future required U.S. Navy capabilities.

This report, intended as a background overview, briefly summarizes U.S. political history with Taiwan and discusses the complications it has for current U.S. policy and for congressional actions.
