A new, less-violent procedure for using nuclear weapons is to give a city "fair warning" before bombing, allow the city time to evacuate, and then not bomb the evacuated city. Using evacuations, rather than nuclear bombings, significantly reduces the potential damage from nuclear war. This allows nuclear nations to conduct a nonviolent nuclear war that neither kills people nor destroys property.
Nuclear weapons are best used coercively, to evacuate cities, rather than actually, to bomb cities or other targets. After a diplomatic solution is reached that resolves the war, people may return to the evacuated cities. Various international institutions and treaties are highly desirable, and perhaps crucial, to ensure that this evacuation procedure works properly and effectively.
