Without a no fly zone Ukraine is doomed. It looks like the lessons of history cannot be learned. See the same kind of waffling and appeasement that lead to WWII spinning out of control. Putin does not care about sanctions or his people. He is an egomanical piece of shit who is driven by a dillusional sense of himself trying to carve out his place in history.
With America's lead a no fly zone can be enforced. American air power is superior to Soviet air power. If you think Putin will use nukes I think it's a bluff. The west should call it.
I don't think Putin wants WW3. I think the Russians have legitimate concerns about NATO encircling them and we were probably building up Ukraine behind the scenes and he put a stop to it. I don't think he starts invading the rest of Europe. I don't think Ukraine is like the Sudetenland was for Germany and that they just keep going.
I agree that if we wanted to enforce a no fly zone we could probably do so, at great cost. But I don't think we should. If Europe is that worried about Russia they should have their own air forces enforce the zone.
