Lmao, if only that was enough to stop the threat of a nuclear war.
I think North Korea is just bluffing, at the moment. It seems like they're only acting tough to gain some respect from the rest of the world; I doubt they actually have the technology to launch a missile as far as the US.
Nonetheless, it's not something we should ignore. The moment he pushes a button, it's going to spark some bad retaliation from the US.
