“This will be effectively like Ukraine is in NATO, but Putin can claim he didn’t cave. But Putin will have given up on part of his overall goal: taking all of Ukraine”
Putin knows enough not to agree to anything obvious fake, as he’ll be hanging by a lamp post if he does.
As to second claim - that may well happen, but if he actually wanted all of Ukraine, he wouldn’t trying to work with Trump, instead he would be following the European plan, which is the complete defeat of Ukraine in order to create a ‘monster’ on Europe’s Eastern Border and thus necessitate the final steps in the complete subjugation of European countries to their one big superstate - that being the EU.
