I think Vexler's interpretation of how Trump feels about and responds to Putin and Zelenskyy, is the one I think is most plausible.
Vlad VexlerTrump still dislikes Zelensky. He doesn't like his raspy voice. He doesn't like his clothes - he thinks Zelensky looks homeless, and therefore, unhygienic. He doesn't like that Zelensky is short. Putin's height, of course, doesn't bother him because he idealises Putin. 1/3
