If the U.S. "inserted" Ukraine's post-2014 government, how come none of the people who rose to power (they were elected, btw!) are even mentioned on the phone call? Did you even listen to it? The only people who saw this as "evidence of meddling" were the Russians and their echo chamber because it was clear the U.S. wanted the new government to succeed!

And why, if the new government was so Nazi-esque, did the Ukrainian government send in the police to take out Muzychko, leader of Right Sector?
