President Obama has renewed his call for nuclear arms reductions – he would like the arsenals of the United States and Russia each reduced by a third. The same valid objections can be raised here that are made about gun control, which is sort of nuclear nonproliferation in microcosm.
No matter how many nukes we get rid of, it is not possible to erase human knowledge of atomic energy. Only the good guys will give up their arsenals. The bad guys won’t, which puts the good guys at a definite disadvantage. We’d be disarming the wrong side.
