The large authoritarian kleptocracy of the United States can just overthrow the legitimate government of a smaller country thousands of miles away like Nuland did in Ukraine in 2014."
Sorry, but that's Russian propaganda, not fact.
The truth is, in 2014, Russia's stooge Yanukovych fled to Moscow, so the Ukrainian parliament declared him removed and replaced by a temporary pro-Ukrainian government which was itself replaced by a duly elected pro-Ukrainian government three months later.
What exactly Nuland or anybody else had to do with this is unknown, and irrelevant.
Ukrainians decided they wanted their own leaders, not Russian stooges.
