I've seen many videos or news of Trump's opinions about this Russia / Ukraine war.
I'm surprised by Trump's opinions (well, always surprised by many things he said during his presidency anyway), but a few things I don't understand,

1. Trump seemingly likes Putin and praises Putin (an opinion shared during this war, not before), why?

2. Trump said he is the first US president under whose watch, Russia didn't wage a war, how should people think about this?

3. Trump said Biden is not a good president, how should people compare them?
