Whats stopping china from helping them?
If we create tension with china what stops them from somehow getting a warhead to korea in pieces, or whatever it takes to keep it a secret, and letting them take full credit and claim they did it themselves?
We keep laughing in their face, not thinking they can do shit, and next thing you know a bunch of americans are dead. the fact is, even if your current opponent's best weapon is shitting in their hand and throwing it at you, you shouldnt underestimate them because they arent the only one on the board.
They want to play propaganda games, flex what they dont have, they should be taught a little fuckin lesson
