If we pretend that's relevant: it'd mean Europe can't be the aggressor either, because Russia did business with them. So I guess nobody invaded anybody?

Meanwhile in reality, Russia invaded Ukraine. Which is pretty goddamn aggressive. And exactly what Europe expected could happen. And in fact, part of what doing business with Russia was intended to prevent. Didn't work. Doesn't mean Europe was somehow at fault for the country that keeps invading its neighbors, invading its neighbors. A country that does so with such regularity, most of Europe is in the Stop Russia Invading Its Neighbors club (which borders with Russia, how dare they!), and Russia still invades its neighbors who aren't in the club. Whilst telling them: this is the stop-us-invading-you club's fault. Which is fucking nonsense.

Anyway your hot take on all this has been shuffling cards in search of relevant excuses, so I think we're done forever.
