“We need to unite globally around opposition to the entire institution of war”

In your website http://worldbeyondwar.org/ you say: “We strive to replace a culture of war with one of peace, in which nonviolent means of conflict resolution take the place of bloodshed”. So which role and value can nonviolence have in building such a culture? It can demonstrate a superior means of resisting tyranny that causes less suffering, is more likely to succeed, and is likely to have a longer lasting success.
