I wonder if a big part of the reason is just the whole phone call about Biden and subsequent impeachment, and how Zelenskyy wouldn’t play ball and the whole thing damaged Trump’s ego in a big way. So even if it’s politically advantageous in every way to say you want Ukraine to win, Trump is incapable of doing so.
It is genuinely amazing. I have watched it multiple times since I first saw it! It feels like something that would be funny but should get old after a few minutes, and yet it never does.
The whole talk appears to be done in one continuous take!
