From the Summary: "There have been sharp debates over the past three decades concerning the appropriate level of funding for U.S. foreign policy programs, and it is likely that these debates will continue as Congress reviews the President's FY2007 budget proposal. The past 30 years have witnessed wide swings in the amounts of U.S. resources committed to advancing foreign policy and national security interests, reflecting changes in global challenges faced by the United States. Efforts to promote peace in the Middle East, to confront Soviet influence, to support new democracies in the post-Cold War era, to fight poverty and disease affecting poor nations, to combat global terrorism, and to stabilize fragile or failed states have had a substantial impact on levels of foreign policy resources. […] This report will be updated as new data become available."
