They ALWAYS threaten to nuke us. Or reign fire down on our skyscrapers.
They are petulant knuckleheads intent on controlling their people and staying in power because it’s the only way they survive and don’t starve.
They will never nuke us.
I agree with your comments. But the situation with NK was not that simple.
The NK’s could have attacked US assets overseas. Then, the US would have to respond. NK would have no choice but to then respond with threats of using one of their secret Nuclear Missiles(whether they would really use it , who can say. Whether they really had a working one, doesn’t matter).
Other nations would be involved, and the whole thing would get out of control. Would we pre-emptively strike NK ? Would the Russians use a Nuke in defense of NK ? Would Middle East countries use the whole thing as an excuse to go after Israel ? Would Israel use Nukes to protect themselves ?
This, I believe, is what Trump was referring to.
