Is that a process where you elect your representatives
Exactly.
toppled in colored coup if not favored by USA?
Unlike dictators, elected officials are supposed to have accountability, and may even be forced to resign if they try sketchy shit like passing authoritarian laws. If USA doesn't favor authoritarians that's probably a good thing but to each their own.
A bit of whattabout, but US has favoured and favours any regime that is prone to let them do business on favourable terms. There is no moral superiority on how the US goes about supporting or not a certain government and that has been clear for decades (perhaps a century now) in Latin America.
Now, for me this is about the people of Ukraine. They need to be able to choose their destiny and my take is that they would rather not be under Adolf Putin and the army Chief Psychos.
