It's good that US is not the only country that has nuclear warheads at their disposal. It's been long enough that they think they are the only superpower country capable of deploying weapons of mass destruction - it's time for them to stop bullying smaller countries.
Economic solution - Korean rocket scientists are paid only US$150 per month only. Pay them $500 and get all of them out of that country and work for US. No more rocket scientist means all the missiles are gounded - got stuck on the launching pad. :thumbsup: :bsmilie:
