From the Document: "Foreign assistance is the largest component of the international affairs budget and is viewed by many as an essential instrument of U.S. foreign policy. On the basis of national security, commercial, and humanitarian rationales, U.S. assistance flows through many federal agencies and supports myriad objectives. These include promoting economic growth, reducing poverty, improving governance, expanding access to health care and education, promoting stability in conflict regions, countering terrorism, promoting human rights, strengthening allies, and curbing illicit drug production and trafficking. Since the terrorist attacks of September 11, 2001, foreign aid has increasingly been associated with national security policy. At the same time, many Americans and some Members of Congress view foreign aid as an expense that the United States cannot afford given current budget deficits. [...] This report provides an overview of the U.S. foreign assistance program by answering frequently asked questions on the subject. It is intended to provide a broad view of foreign assistance over time, and will be updated periodically."
