That's a very reductive description of the orange revolution and euromaidan, though.

In both cases, the US didn't come in and overthrow the Ukrainian government, there was no assassination, no military coup. At a stretch the most you could reasonably argue the US was involved was egging them on.

It was just an enormous number of Ukrainians protesting the abuse of their political system.

The first time, because the president ordered the kidnapping of a journalist ON VIDEO (whose body was then found, decapitated) then attempted to rig the election in favour of his successor - this resulted in massive protests until the election was re-run (this time with international observers) at the demand of their own supreme court.

The latter because the president ran on a platform of EU alignment, then immediately betrayed the people who elected him by doing the exact opposite in order to placate Russia. He was then removed by parliament, who had a legal right to do exactly that.

Note how, both times, the government was removed, not by a couple, but by the legitimate political institutions of the country.
