Err, yes, I would be surprised, no I don't think Russia will. But its like, surprised if bitcoin dips below 20k next week, not outside the realm of possibility.

That was what I thought at first, that they wouldn't escalate that far. If there were enough NATO supplied military assets within Ukraine, they would strike those first because it would get the same benefit (reduction of the enemy's military assets) while being less provocative. I guess I've changed my prediction.
