Extremely good points.
Shows how he's miscalculated though. Rather than guarantee his country's economic future, he's pretty much doomed it.
That said, and this is a question for everyone here- if Russia start to negotiate, and pledge to withdraw right now IF we remove sanctions, would you take that offer? Not that he could because he would be seen to have lost the war by his own people, but just as a hypothetical.
I don't want people to die in Ukraine, but Putin must not be allowed to do this, or anything like it again. Plus, how much are the Russian people, who are not responsible for this war likely to suffer under sanctions. Tough call.
