Kim Jong-un is a joke

I laugh when the dictator Kim Jong-un speaks that will annihilate the United States, with that technology of the 60s, the United States is the greatest military potential in the world, if they wish they would do the regime of kim jong-un turn to dust.
Thats not the real problem, the probleme is a world war because of usa russia china, kim jong is a little small boy playing with big toy but alone.
I believe that China and Russia would not move a finger, but attacking North Korea would be a serious problem for the United States, as well as spending a lot of money, the international community would be against, thus causing the United States to lose influence
