This is deterrence, it just so happens that the United States of Amerikkka doesn't like it when you limit their options from mass genocide, to "infantry invasion".
Does deterrence work? It does until it doesn't. The only country that has ever used nuclear weapons against another country is America, so we'll never know until it happens again. And when it happens again, there won't be a society to sort through the evidence and ascertain blame.
This is a good time to remember that Americas nuclear war strategy is to be the largest standing civilization after the ~2 hours of nuclear holocaust. Unironically.
The world has some serious doomer vibes. I really think the ruling class knows the world is fucked and instead of doing something to fix it, they are like nothing matters anymore, let's go out with a bang approach.
Hey, this is incredibly rude. I am speaking to the ruling class in America and their objectively bad policy of belligerence in an attempt to bring down the world with them, and how the world is being looted by capitalist. I am not criticizing Russia and DPRK.
And immediately after that, Occupied Korea announced that it want to deliver weapons to Ukraine. No shit, now they can't just attack DPRK so they need to get rid of the arsenal they've been producing for years and are trying to check if the dumb eurocrats will pay for it.
