Name the President of Argentina who was overthrown during the 1976 coup d'état, which disrupted a planned guerrilla operation by the PVP of Uruguay which included exiles in Argentina?
Partido por la Victoria del Pueblo The Partido por la Victoria del Pueblo, also known as the Party for the Victory of the People or People's Victory Party (PVP), is a political organization in Uruguay. Its military wing is known as OPR-33. The leftist group began under an anarcho-syndicalist philosophy and was overshadowed by Tupamaros in Uruguay. The Party grew in strength among exiles in Argentina, both in followers and money, with $10 million from the successful ransom for a kidnapped businessman. Their planned an guerrilla operation to reclaim its place in Uruguay went awry with the surprise 1976 Argentine coup d'état. Several days after the coup, three PVP members were arrested while attempting to cross back into Uruguay. The arrests continued through the other group members in Argentina, dozens in total, including its leaders, in concert with Uruguay security forces.
Carlos Manuel Arana Osorio Carlos Manuel Arana Osorio (17 July 1918 – 6 December 2003) was President of Guatemala from 1 July 1970 to 1 July 1974. Arana Osorio was born in Barberena, in the department of Santa Rosa. A colonel in the Army, he was elected in an electoral process generally considered "non-transparent" on a platform promising a crackdown on law-and-order issues and stability; his vice president was Eduardo Cáceres. In November 1970, Arana imposed a "State of Siege" which was followed by heightened counterinsurgency measures. The government received continued large-scale military support from the United States, which provided weapons, technical support and military advisors to the security forces under Arana to assist in fighting the guerrillas. The systematic use of state-terrorism which emerged in 1966 under President Julio César Méndez persisted under Arana; government-sponsored "death squads" remained active and the security forces regularly detained, disappeared, tortured and extrajudicially executed political opponents, student leaders, suspected guerrilla sympathizers and trade unionists. It is estimated that over 20,000 Guatemalans were killed or "disappeared" under the Arana administration.
