Query: for years the us has tried to dissuade NK from developing nuclear weapons and the delivery of them via missiles and has failed miserably.  America is paranoid that only they should have nuclear weapons.  but since the first nuclear weapons were fired, many other countries have developed the capability, Russia, china, Pakistan, india.  while these countries have the weapons, they have not used it in warfare.  they all know the devastating effects of it and are reluctant to use them and even Russia instead of using nuclear weapons have only used conventional warfare.  so, is it so bad that NK have these weapons?  being a small country, can they really be a nuclear threat to any other country?  hence, actual facts show that nuclear nations will not use such weapons, knowing full well that they can be annihilated if they did so.  America should pull out of SK and let them and NK resolve their differences and become united again.  we failed so time to let them do it, as in Vietnam.
