He's a war leader. He can't afford to show weakness to Russia, the World, and most importantly his own people. Ukrainian position is clear: they won't support a meaningless 'deal' just because Trump wants them to, whatever the consequences. IMO it's clear that US wants out ASAP, ideally but not necessarily with a cosmetic Trump-dictated 'deal'.
Trump's right about one thing: they're going to have to fight it out. I think everyone knows this.
And I don't even think it's hidden that Trump is using poor Ukraine as cover to engage on economics with Putin. Hey ho.
