A catalyst. Problem, reaction, solution. Have one rogue nation with nuclear arms attack ANY country with one of their nukes. We have a problem. People put a flag filter on their facebook/twitter avatar and beg their own governments and the United Nations to do something. We have a reaction. The mockingbirds push for a world regulatory body to ensure that something like this NEVER happens again, swaying the easily manipulated masses into the belief that this will solve the problem. We have the final solution. End game. Humanity loses.
