Why would anyone agree to a complete capitulation, and paying reparations, and giving up land and people under the current conditions? Oh, and the US removes it's forces from the Baltics at the same time, Ukraine gets absolutely nothing except for a temporary ceasefire with no security guarantees.
I mean - it's just so completely obvious that Trump fully and completely works for the Russians. Full stop. They are coming with the exact same absurd Russian maximalist goals, zero concessions. But - what leverage do they have to tell Ukraine to accept it and that's that? Fine - pull your support, America. Ukraine still has cards to play. Agreeing to your terms is literally signing your own death warrant, now or later.
