Well EU is not far behind. But yes, if you damage country by attacking it and literally erasing towns in it, and capturing territory (the one you guaranteed to preserve and even defend by previous agreements), expect to pay.
Wait, are you telling me US will be paying reparations to all the countries it bombed to the ground? Vietnam, Laos, DPRK, Afghanistan, Iraq, just to name a few?
It's true, I still remember when the rest of the world put those heavy sanctions on us for our barbaric and genocidal invasion of Iraq. It was tough, but that was the day I learned that international law is definitely a real thing.
