Putin would have anticipated that he could get you know Ukraine handed over without the necessity of invading so if you look back to what happened in the run-up to the war there's the Geneva meeting between Biden and Putin. He's trying to figure out whether Ukraine really matters and is pushing Biden to basically negotiate away Ukraine a bit like Yeltsa 1945 and Roosevelt and Churchill and Stalin again. "Biden isn't willing to negotiate Ukraine it's not the United States to negotiate a war same you know on Europe as well"
