I’d call it a pyrrhic victory at best. It’s like if Ukraine got Russia to use their nukes on them and there was no response from the rest of the world. Sure, you got them to use their strongest weapon, but you still got nuked and they’ll continue as usual.
there’s this little human thing called emotions that you might have missed, and some people are real bad at controlling them. the reasons behind that can be varied, but often they have a stake in the game (as in they’ve bet on it or similar).
