Would you be happy to give a bunch of pre-school children some weapons of mass destruction and "let them launch and see what happens"? I admit that we can't be sure what would happen, but personally I can't see how the outcome could possibly be good. Assuming they have to exist at all, weapons of mass destruction are better off in the hands of responsible state actors, rather than a group of people who have absolutely no idea of what they're playing with let alone developed enough emotional maturity for dealing with the consequences of using them.
