Well here are some factual problems with your post:
1) "Trump and Vance ambushed Zelensky"
Zelensky wasn't ambushed, he was the aggressor. He began lecturing Vance when Vance was asked a question about Putin. That is what kicked the whole debacle off. You can say his point is valid, I get it - but prior to that the tone of the meeting was very gracious from all involved. It was Zelensky that broke diplomatic protocol.
2) "This has been the plan all along."
Wrong, Trump wanted a peace deal. Part of the peace deal was the mineral deal. A lot of effort had been put into that. Everything else was negotiation. That includes the (pointless) UN vote. Earlier today, Trump literally
extended sanctions on Russia. That's actual policy. Now did Trump insult Zelensky recently? Absolutely, because Zelensky was showing his ass then too. But Trump also laughed off his comments yesterday "did I really call Zelensky a dictator? I can't believe I would." Now that may infuriate you - I get it - but that is what Trump walking comments back looks like.
3) "Even the stupid comments about Zelensky's attire"
That was a media question, that was not from Trump or Vance.
4) "All with not a single word about Russia or Putin."
Trump explicitly addressed this. "You want me to say really terrible things about Putin and then say, 'hi, Vladimir. How are we doing on the deal?' It doesn't work that way. I'm not aligned with anybody. I'm aligned with the United States of America, and for the good of the world."
5) "I'll wager that we will end all aid, and it will lead to what will likely be an end to the NATO alliance within two years."
You could be right about this. If so, the blame is with Zelensky for the way he acted. It was objectively stupid. He placed his ego ahead of his cause, that's a basic failure of leadership.
