A.N.S.W.E.R. (Act Now to Stop War and End Racism)—also known as International ANSWER and ANSWER Coalition and sometimes written as "ANSWER"—is a protest organization established by the International Action Center, which was founded by former United States attorney general Ramsey Clark and has taken a leading role in the post-9/11 antiwar movement. The organization characterizes itself as anti-imperialist, and its steering committee consists of socialists, civil rights lawyers, and progressive organizations from the Muslim, Arab, Palestinian, Filipino, Haitian, and Latin American communities.
It has organized many of the largest anti-war demonstrations in the United States since the September 11, 2001 attacks, and has also organized activities around a variety of issues, ranging from Palestine, to immigrant rights, to Social Security, and the extradition of Luis Posada Carriles. Though its national headquarters are in Washington, D.C., where it organizes its national antiwar demonstrations, the coalition's influence is seen as being strongest in San Francisco, and increasingly, in Los Angeles.
A.N.S.W.E.R. was one of the first organizations formed to protest the policies of the Bush administration in the wake of the September 11 attacks. Their first major action was a September 29, 2001 "Anti-War, Anti-Racist" political rally and march in Washington, D.C., primarily in protest of the then impending U.S. invasion of Afghanistan. An estimated 8,000 people participated; other rallies organized by ANSWER in protest of both that conflict and the 2003 invasion of Iraq have been even larger.
