War resistance in the United States encompasses activities related to war resistance by American citizens and other who oppose military action on the part of the United States. This includes opposition to, and evasion of, military duty. Such resistance may originate from pacifism, antimilitarism or non-interventionism, generally, and may include registration as a conscientious objector to military service, draft dodging, or desertion. Alternativelty, it may be directed towards specific military actions, as with opposition to the U.S. involvement in the Vietnam War, opposition to the Iraq War, and the post–September 11 anti-war movement.
