The problem with those in the West who self-promote as experts on international strategy, particularly pertaining to countries like Russia and the leadership there, IMO, display a complete lack of understanding of the mindset. I really don't think anyone has a crystal ball for telling the future of when Russia or Putin just says, "I give". In the meantime, the US keeps pumping money and international political capital into a proxy war hoping for that eventual conclusion. Seems like history is replete with that type of wishful thinking. This error in this thinking even gets supported by nuances of theoretically comparable history like... "well, Russia pulled out of Afghanistan because it wasn't fighting for Mother Russia". Or... "Stalin only tried for 3 1/2 months in the Finland Winter (suicide) War and doomed 50,000 to 125,000 troops (even historians can't agree on the number) but gave up because that action was not exactly defending Mother Russia". For anyone to think and promote the idea they are a mindreader in these matters is treading in dangerous territory, IMO. It would be wise to play "devil's advocate" a bit here. Self described experts currently like and are actively selling the idea that just a "little more" and Russia with cave and give up on Ukraine. Offering such "proof" as, see here, "Stupid Russian commanders sent 2 APCs and a tank into a Ukrainian trap and were destroyed" see, see, "just a little more and Russia (Putin) will give up". Or same "experts" will float the domino theory for the rest of Europe.... "if we don't stop them now....". The domino theory has not played out well if history is any teacher. And the Russian mind-reading experts would have everyone believe that since Russia (Putin) is not fighting for Mother Russia in the Crimea or SE Ukraine they will give up if we support the proxy "just a little more, for just a little longer". How long? 5 years? 20 years? Playing a "devil's advocate" debate might be wise. Just suppose that the Russians particularly the leadership and Putin actually do think of the Crimea and SE Ukraine as Mother Russia!
