A worker in New York City, observing the rubble of the World Trade Center, after terrorists hijacked passenger planes and crashed them into the buildings on September 11, 2001. The first time in which the United States was attacked on its home soil since 1941, the terror attack served as a “rally around the flag” moment, where the United States public was willing to fully support the government in combating terrorism. This new threat, however, presented a major challenge: how to combat terror groups that operate without borders, and without a government? A challenge the United States still faces today.
