"berating the Ukrainian president during an Oval Office shouting match"
You may need to watch the meeting. And be aware Zelenskyy was supposed to sign an agreement already approved in Ukraine but screwed it up. And apparently had been like that for 40 minutes before the cameras had been on.
Note that the loss of US support brought Zelenskyy to the negotiating table and Trump also threatened Putin to behave as well as convincing him to accept a ceasefire. Both things rules out completely under Biden.
These negotiations achieved while the US 'allies' insisted on lobbing missiles into Russia to coincide with the arrival and departure of the negotiators. But no Europe cannot make up for American support and this is a big problem that Trump pointed out in his last administration.
