What if instead we simply air-dropped millions of cheap weapons (something like the Liberator pistol, a simple .357 revolver, or bolt-action rifles) into a distressed area at the first sign of genocide? Just saturate the country with weapons, then move in with peacekeepers later? Mobilizing troops takes time. What's wrong with saturating a country with purely defensive weapons? First, do you think it would stop genocide or slow it down? Second, what might the unintended consequnces be?
