On September 11, 2001, people in the United States became aware of international terrorism in a way they may not have understood before.
The same could be said about the United States as a nation. Along with the international community of U.S. allies. Some responses to the attacks were immediate. Some took place weeks after the attacks. Some took years. However long, September 11, 2001, changed the United States, its people, and the world forever.
