The United States and its allies are helping Afghanistan emerging from more than 22 years of warfare, although substantial risk to Afghan stability remains. Before the U.S. military campaign against the orthodox Islamist Taliban movement began on October 7, 2001, Afghanistan had been mired in conflict since the Soviet invasion of Afghanistan in 1979. The defeat of the Taliban has enabled the United States and its coalition partners to send forces throughout Afghanistan to search for Taliban and Al Qaeda fighters and leaders that remain at large, including Osama bin Laden. As the war against remaining Al Qaeda and Taliban elements winds down, the United States is shifting its military focus toward stabilizing the interim government, including training a new Afghan national army, and supporting the international security force (ISAF) that is helping the new government provide security.

This report lists 234 instances in which the United States has used its armed forces abroad in situations of conflict or potential conflict or for other than normal peacetime purposes. It brings up to date a 1989 list that was compiled in part from various older lists and is intended primarily to provide a rough sketch survey of past U.S. military ventures abroad. A detailed description and analysis are not undertaken here.

This report provides an overview of the Muslim separatist movement in China’s northwestern Xinjiang Uighur Autonomous Region, China’s attempts to stifle activities which it considers terrorism, and implications for U.S. policy. Some analysts suggest that the U.S.-led campaign against terrorism may make it difficult to pressure the Chinese government on human rights and religious freedoms, particularly as they relate to Uighur Muslims in Xinjiang.
