The document discusses developing a realistic alternative to war and other violence for resolving acute conflicts where fundamental issues are at stake. It argues that nonviolent action provides a substitute for violence that is a powerful means of waging conflict without relying on war. Nonviolent action has been successfully used across many cultures and centuries in a variety of conflicts against oppression, dictatorship, invasion, and other threats. When fundamental issues are involved, nonviolent action can replace violence as the means of last resort for defending principles or existence without submitting to the opponent.
