See that last stipulation is problematic. You are saying give an example but you are filtering out every possible example which would be when one side refuses to come to the negotiating table. Now granted im not saying you are wrong but in evaluating and thinking of an answer the problem of the logic with the when statement immediately pops up. Non violent protest leads to negotiation. bzzz. can’t use it. As I said in another post violence will happen. One side can be nonviolent but I can’t think of a case where they were nonviolent and violence was not done to them.
