That’s assuming the EU won’t respond, or for that matter Poland being incapable of pushing back Russia all by itself.

Them and what army? The only countries on Earth with enough firepower to stop Putin without launching any nukes are the US and China, and China is on Putin's side.

There’s about exactly one single reason why the Poles aren’t parading on the Red Square right now: Because they’re in NATO, which acts as a leash.

I assume this is some kind of joke.

Finland would get pulled into it because of their own attitude and Estonia, and with them, without fail, Sweden. At which point Germany would have a hard time holding back and then it’s guaranteed that the French will be in the fray, and that’s presuming they wouldn’t have been as soon as Poland lets loose because principle.

Last I heard, Finland and Sweden had been taken over by Nazis, and Germany was in the middle of being taken over by Nazis. I'd expect them to welcome Putin's invasion with open arms. France is too busy fighting itself to fight anyone else.

But in the end once the EU is involved the US will be, too, because the US can’t countenance Europe doing something militarily without joining in.

At which point we're back to square one. The reason we're having this discussion is because, in the opinion of @Roody15@reddthat.com, it is “very sad” that the US isn't going to sit back and let Putin start World War 3.
