Let’s start with this: Ukraine is losing the war, and the longer it goes on the worse the peace deal will be. I absolutely agree with Trump that there needs to be a peace deal, and soon.
But the rhetoric coming out of the Trump administration and its proxies suggests that Ukraine owes America nothing, and that indeed, Ukraine owes America for all its support. This sounds reasonable, on the face, but only if you don’t know any history.
Let’s start with the 2014 Maidan protests which overthrew the government. They were a color revolution, heavily supported by the Americans and Europeans. Say what you will about Yanukovych, he was the elected President. There’s decent evidence that the sniper massacre was done by Maidan itself (see this academic study), and post coup, Ukraine was essentially run by Victoria Nuland.
