The article also refers to the Tuskegee syphilis experiment, in Alabama, which involved hundreds of African-American men (1932 to 1972).
A Tuskegee researcher, Susan Reverby, discovered the records, which indicate the project in Guatemala was sponsored by the U.S. Public Health Service, the NIH, the Pan-American Health Sanitary Bureau (the Pan American Health Organization) and the Guatemalan government.
The article also mentions how the the CIA, in 1954, overthrew Guatemala's democratically elected government, on behalf of the multinational United Fruit Company, because of land reforms.
Wikipedia has information about the involvement of public relations pioneer, Edward Bernays, in the overthrow.
This information confirms the nature of the regime which is still in power, the faction of totalitarians who emerged from World War II as the "winners", and have gradually accumulated more power. They are globalists, they are eugenicists who experiment on human beings. They recruited the Nazi scientists after World War II, and other atrocities. They dropped the atomic bombs on Japan. They do not believe in morality. They are co-called "capitalists" but they do not believe in free market for ordinary people or property rights or freedom, and this is why these things have been eroded over time in America. They are liars. They are monopolists and imperialists who are continuing to implement collectivist policies, putting into place the last planks of the so-called "Communist" manifesto after pretending to be anti-Communist throughout the Cold War. That's their false dialectic which confuses so many of us to this day, which makes us take sides and choose between their fake factions. But it's evident in the writings of H. G. Wells and Zbigniew Brzezinski that the dominant ideology is a technocratic population-obsessed internationalist blend of totalitarian "socialism" with depersonalized methods of big business "capitalism".
