I've watched it. I disagree. Zelensky calmly and reasonably asked JD Vance a question regarding his answer to the reporter. It was all fine until Vance started with the "frankly I think it's very disrespectful" line. HE decided to escalate. What Zelensky asked was reasonable and pretty in character for him. They know he's uncompromising with dealing with Putin. The _diplomatic_ position is to understand both sides and mediate, not to try to get one of the sides to bow down to their aggressor.
