Act Now to Stop War and End Racism (ANSWER), also known as International A.N.S.W.E.R. and the ANSWER Coalition, is a United States–based protest umbrella group consisting of many antiwar and civil rights organizations. Formed in the wake of the September 11th attacks, ANSWER has since helped to organize many of the largest anti-war demonstrations in the United States, including demonstrations of hundreds of thousands against the Iraq War. The group has also organized activities around a variety of other issues, including support for Palestinians, immigrant rights, Social Security and opposition to the extradition of Luis Posada Carriles.
