I had no problem with Zelensky. Or the fact he would think the US would and probably should support his country's defense of their sovereignty intact.
It is not like he threw it up in Trump's face, that the only reason, Russia was able to start this war of aggression against Ukraine is because Ukraine agreed to turn over their nuclear weapons to the US for destruction, under an agreement brokered by the US, in conjunction with Russia, guaranteeing Ukraine's security from attack by Russia, even though, Russia had already broken the agreement and now possibly the US was, also.
