No doubt the U.S. supported the Maidan Revolution (which was irresponsible), but they couldn't have caused it. Some Ukranian people caused it.
That's pretty much irrelevant now. We must deal w/ the present and move forward.
Here's my take: Ukraine was a dysfunctional state in 2014 and Russia got Crimea. Uk did nothing about it until the 2022 invasion. Too late and there's little they can do now. Trump is right, Z must finally cede Crimea.
Cede existing areas where Russia has control of the Donbass, nothing more.
Z. will not like this.
Security guarantees for what's left of Uk. and once they get their politics in order allow them to join the EU.
Putin will not like this.
But that's what happens in a negotiated settlement, neither side gets all of what they what.
