So when the OAS [0] fraudulently, according to the Guardian, the New York Times, and every subsequent study, accuses the legitimate Bolivian elections to be fraudulent, after which a well-coordinated coup by the military and the far-right establishes a dictatorship that keeps postponing elections (Haven't seen that happen in Egypt before), that is also completely coincidentally the group supported by the government of the United States despite the press, academia and intelligentsia of the country recognizing that the elections were legitimate, that is not a US-backed coup?
Because it seems to me that it was a coup. That was backed by the US. Which makes it a US backed coup.
[0] The OAS is a cold-war era organization that was literally founded in order to instrumentalize the Monroe Doctrine. Moreover, the current chairman of the OAS publicly states his support for regime change, and the organization is largely funded by the US. It was designed in order, and still largely acts, to implement US foreign policy.
The CIA literally had a budget in order to remove Allende from power. One of their top priorities was to fund, cause, and instrumentalize a military coup in order to remove Allende, which happened exactly in the timeframe they planned, and was executed by the actors that they had counselled and financed for the past two decades in the goal of removing any left-wing president : https://en.wikipedia.org/wiki/United_States_intervention_in_.... It is absolutely certain that the US was instrumental in the overthrow of Allende, with the CIA even publicly taking credit for creating the conditions that led to the coup. After the coup, the US politically and economically backed the military dictatorship. So yes, the US caused, and backed the coup. He was overthrown by his own military, that were organized to perpetrate a coup by the US.
It is literally a pattern of machinations. There aren't a series of dozens of coup d'états that mysteriously happen in countries with CIA activity that also happened to be against US interests, and that turned out exactly to further US interests. The CIA didn't make contacts in the militaries, in supranational organizations, and with local interest groups for fun.
