The Cold War was the major focus of most of our foreign policies, which dictated the nature of engagements with other nations and often involved not only the use of military force but also a combination of covert operations in addition to economic and diplomatic tools. Ultimately the United States emerged victorious when the Soviet Union collapsed in 1991. However just a decade later in 2001 the 9/11terrorist attacks on the World Trade Center sparked a new era of War, one waged on Terror which has replaced the Cold War as the focus for international foreign policy.
