"In the summer of 1950 in South Korea, anticommunists aided by the US executed at least 100,000 people suspected of supporting communism, in the Bodo League Massacre. For four decades the South Korean government concealed this massacre. Survivors were forbidden by the government from revealing it, under suspicion of being communist sympathizers. Public revelation carried with it the threat of torture and death. During the 1990s and onwards, several corpses were excavated from mass graves, resulting in public awareness of the massacre. 1"
"In 1965, The CIA overthrew the democratically elected Indonesian leader Sukarno with a military coup. The CIA had been trying to eliminate Sukarno since 1957, using everything from attempted assassination to sexual intrigue, for nothing more than his declaring neutrality in the Cold War. His successor, General Suharto, aided by the CIA, massacred between 500,000 to 1 million civilians accused of being communist, in the Indonesian mass killings of 1965-66. The US continued to support Suharto throughout the 70s, supplying weapons and planes.
"In 1969, The US initiated a secret carpet bombing campaign in eastern Cambodia, called, Operation Menu, and Operation Freedom Deal in 1970. An estimated 40,000 - 150,000 civilians were killed. Nixon lied about this campaign, but was later exposed, and one of the things that lead to his impeachment. 1"
"From 1982-89, The U.S. government attempted to topple the government of Nicaragua by secretly arming, training and funding the Contras, a terrorist group based in Honduras that was created to sabotage Nicaragua and to destabilize the Nicaraguan government.As part of the training, the CIA distributed a detailed "terror manual" entitled "Psychological Operations in Guerrilla War," which instructed the Contras, among other things, on how to blow up public buildings, to assassinate judges, to create martyrs, and to blackmail ordinary citizens. In 1986, the Nicaraguan government under the Sandinistas shoots down a C-123 transport plane carrying military supplies to the Contras. The lone survivor, Eugene Hasenfus, turns out to be a CIA employee, as are the two dead pilots, contradicting Reagan's claims that the US was not aiding the contras. 1"
These are only a couple of examples of US Imperialism. Deny this. I dare you.
