Edit: if you flipped it on it’s head, this war is like if Mexico had a revolution that overthrew their corrupt government, and while the protests were happening Russia was supporting key members of the ones overthrowing the government.

It’s obviously not right that Russia is fucking around in Mexico’s revolution. But in this case, Russia doesn’t care if Mexico beats back the invading US, they just want to keep supplying them with weapons to prop up Russia’s own domestic “defense” industry, prop up the economy, claim moral necessity, unite the party against a common enemy, bobs your uncle, you’re elected again
