Bolivia has had instability in their leadership in recent years. So the US can just say that the most reactionary faction/party is the true Bolivian leadership and that the US just wants to help get rid of the usurpers.

It wouldn't be the first time the US gets involved in Bolivia. I happen to recently have stumbled upon a short document on Wikileaks that sported "Bolivia", "cocaine coup", "CIA", and I shit you not, "Unification Church" and "SS veteran Klaus Barbie" all in the same paragraph.

Has that ever worked out in the long term though? Some of the fiercest enemies of the us were forged that way (IRAN, whole south america).

The imbeciles with three letters are a liability in a multipolar world, driving potential allies towards perceived "underdog" opponents.

That whole dirty game did not even work during the cold war. Most victories were economic prep ups for countries sliding towards the opposition, the whole regime take over propelled a ton of countries towards a opposition that would have otherwise just stayed neutral and independent from ex-colonial powers. Without the colonial powers and the CIA pushing, there would have never been a domino effect to take note off.
