Seems like you're claiming Ukraine's 2014 "Revolution of Dignity" and subsequent democratic elections were something the USA did. That's a controversial claim, and one that ignores the recorded actions and sentiments of the Ukrainian people. It's also unrealistic and gives the US too much credit.

The US does have their hands in pies across the globe, but that was a large scale uprising of Ukrainian people. No outside force can make something like that happen if the people aren't already aligned.

The simpler explanation is the Ukrainian people wanted to be closer to the EU, and didn't like Yanukovych's authoritarian tendencies. I wouldn't be surprised if some propaganda blamed it on the US, but it doesn't make sense. If the US wanted to do regime change and the public wasn't behind it, it would look very different. There are unfortunately many examples.
