Honestly, I don’t even think this kind of sentiment/outcome is necessarily Trump’s fault, but rather the outcome of US overall goal for Ukraine - in another article I’ve seen Joe Biden acting disappointed towards Zelensky for not being “grateful”, but privately.

It seems they REALLY wanted those mineral rights and then a ceasefire so they could extract them and hold heavy political influence over the country, much like how foreign oil companies backed by the US hold heavy influence in democracy/austerity in the global south.
