Are We Supporting Ukraine to Maintain a Sovereign Ukranian State?

Am ino: Most people who are realists through restrain s to this war have been, in many ways, quite similar to liberal internationalist perspectives. But i do think there are some big differences now that we are a sort of three months into the war. There's differences on the costs that the west be willing to bear and how important ukraine is. Am at least more concerned about the notion that this could escalate horizontally to a broader european war or vertically to a nuclear war.
