The Jews illustrated this in the Warsaw Ghetto uprising. A small group of brave people with guns obtained from killing Germans individually held off the German army for over a month. They proved that self defense and fighting back was preferable to going passively to the trains for transport to a death camp. The fact that most Israelis today are members of the military reserve and have received training in weapons and have weapons at home has resulted in less gun violence on the streets of Israel. They don't just conceal their weapons; they carry them in the open on the street. An AK is a fine deterrent to street crime. Unfortunately, a gun isn't a good defense against a bomb.
