The term anti-war sometimes refers to pacifism, i.e., opposition to all use of military force during conflicts, but most often is used in the context of opposing one particular nation's decision to wage war. Many activists distinguish between anti-war movements and peace movements. Anti-war activists work through protest and other grassroots means to attempt to pressure a government (or governments) to put and end to a particular war or conflict. (wikipedia)
