Putin will ultimately win. Because the west is run by un-serious posers and putin knows it. He does not give a **** about mean tweets about him. He does not give a **** if they confiscate a few yachts. He does not give a **** about sanctions on paper that do little in real terms. Basically, he's The Pats cheating because they know nobody will do anything about it.
He will likely walk away with key areas of Ukraine that will build up Russia's oil production even more. Plus his enemies will spend hundreds of billions rebuilding Ukraine. Then after all the tough talk, they will keep buying Russian oil.
The world is about to experience a food shortage due in large part to loss of production in Ukraine. If there were serious people in charge, they would tell Putin that they are sending troops into Ukraine to protect the farm lands and the people working there and if russian troops go anywhere near them, they will invade and take back crimea and set it up as neutral NATO territory forever.
Biden and others just want to talk tough, do little and then when it's finally over, they will claim that it was their tough sanctions that stopped Putin. Then back to doing business with him.
