アントニオ・サラザール
After conflict erupted between the UPA and MPLA and Portuguese military forces, U.S. President John F. Kennedy advised António de Oliveira Salazar (via the US consulate in Portugal) that Portugal should abandon Portugal's African colonies. A failed Portuguese military coup known as the "Abrilada", attempted in an effort to overthrow the authoritarian Estado Novo regime of António de Oliveira Salazar, received covert U.S. support. In response, Salazar moved to consolidate his power, ordering an immediate military response to the violence occurring in Angola.
