As usual, Donald Trump just doesn't get it, living as he does on a complete different planet from the rest of us.
Inserting himself into yet another situation where he's not really wanted, Trump is "making deals" with global pariah, Vladimir Putin, presenting a peace plan for the 3-year old war in Ukraine without even involving Ukraine (or Europe).
Trump is desperate to earn himself the Nobel Peace Prize, and his simplistic conception of brokering peace is to offer his buddy Putin whatever he wants, Ukraine be damned. So, as far as he is concerned, Russia can keep the Donbas and anything else they might have illegally annexed, and he is quite happy to conclude a deal - on behalf of Ukraine - assuring that Ukraine will never join NATO (another of Putin's stipulations), which would be the only thing standing between Ukraine and another invasion by Russia a few years down the road, to finish the job once and for all.
Trump doesn't care about Ukraine, nor does he care about morality or "doing the right thing". That is not who he is. All he cares about is his legacy and what makes money for the USA. With gob-smacking cynicism, he is tying further support for Ukraine to American access to Ukrainian rare earth minerals. He blithely deadpans, "They may be Russian someday or they may not be Russian someday". His scorn and arrogance knows no bounds.
Ukrainian President Zelenskyy is being understandably carefully in his public remarks about Trump, buy he must be seething inside. Europe is, perhaps rashly, being less careful in its language, using phrases like "dictated peace", "appeasement" and "dirty deal". Trump has already made clear that he is not willing to bankroll Ukraine further, and has even indicated that Europe can no longer rely on the USA's help with its own security. Let's hope it doesn't get any worse.
