The terrorist attacks on September 11th 2001 brought increased attention to Muslims living in the United States. Results from four national polls of Muslim Americans conducted between 2001 and 2007 indicate that Muslim Americans feel increasingly negative about the direction in which America is heading and increasingly see the war on terrorism as a war on Islam.
