In no particular order:
Iran
Guatemala
Chile
Nicaragua
Granada
Panama
Angola
Argentina
That's just a few... you could easily treble or quadruple the number of countries involved and find a lot more information about such actions, many against democratically elected governments, governments about to come into power legitimately or popular revolutionary governments.
What exactly surprises you that leading governments - not just the US - secretly and illegally supply weapons, stage coups, raise insurrections, aid despots, train death squads, etc, etc, etc...
This type of behaviour is not random. It has ends. Your welfare is not one of them.
