Did the US overthrow Guatemala in 1954?

Yes, the United States overthrew the democratically elected government of Guatemala in 1954 in a covert operation known as Operation PBSuccess. The operation was carried out by the Central Intelligence Agency (CIA) at the behest of the Eisenhower administration. The main pretext was that the government of President Jacobo Árbenz Guzmán was communist-leaning, which was seen as a threat to US interests in the region. The operation was successful in overthrowing Árbenz and installing a military dictatorship led by Carlos Castillo Armas.
