I don’t think Putin will accept anything but total victory.
I think it (Russia's results) would have to be pretty close to that.
Otherwise, how can Putin justify the horrendous cost?
It's pretty clear though, that Trump, and no likely US President, will accept a "pretty close to" Russian "total victory". Moreover, that cost I allude to doesn't even consider the baggage that comes along, including a doubling of NATO's direct border with Russia (and Norway driven firmly into the alliance -- Norway is no Hungary), holding Ukraine and suppressing partisans (a giant version of Israel and the Palis?), hostility of the Euro's vs. a comfortable and very profitable business relationship, and more important, a ramping up of Euro-NATO countries' defense spending that near triples their expenditures. Worst of all for Russia, Russia's been driven into China's arms. Given the direction China has taken under Xi, that's not merely like Eve eating the apple, it's like marrying Satan himself.
Igor Girkin seems to understand some of these things, but even he, IMO, doesn't fully "get it". Yet.
