Vance is like Ben Shapiro with a little bit more intelligence.
Zelensky had some translation issues, perhaps, and said something in a strange way. But Trump's outburst was like that of a run-of-the-mill dive bar moron, not a diplomat.
Zelensky's interview with Bret Baier was also subtly hostile. Z never said the words "apologize" or "sorry" but did express regret that the conversations happened as they did in public. He was repeatedly grateful of the support of the US and was showing quite a lot of understanding.
The arguments of the Fox panel, if you cut through the lines, is that it is Zelensky's fault for not knowing how to handle the intellectual child that is the US president.
