The USA will put too much vaseline in the hole and then they will attack to N. Korea and Russia with the ass. lol
If the United States is going to invade North Korea, I really doubt whether Russia or China would do anything to help Kim Jong Un. That said, there is a chance that they will send some weapons to the fat boy. But sending soldiers to North Korea is perfectly out of question. I really hope that such an invasion never happens. If it occurs, then Japan, South Korea, and Hawaii will become nuclear wasteland.
