According to Secretary of State Madeleine Albright, terrorism is the most important threat the United States and the world face as the 21st century begins. High-level U.S. officials have acknowledged that terrorists are now more likely to be able to obtain and use nuclear, chemical, and biological weapons than ever before.

Yet most attention has been focused on combating terrorism by deterring and disrupting it beforehand and retaliating against it after the fact. Less attention has been paid to what motivates terrorists to launch attacks. According to the Pentagon’s Defense Science Board, a strong correlation exists between U.S. involvement in international situations and an increase in terrorist attacks against the United States. President Clinton has also acknowledged that link. The board, however, has provided no empirical data to support its conclusion. This paper fills that gap by citing many examples of terrorist attacks on the United States in retaliation for U.S. intervention overseas. The numerous incidents cataloged suggest that the United States could reduce the chances of such devastating–and potentially catastrophic–terrorist attacks by adopting a policy of military restraint overseas.
