There are conspiracy theories all around us and we don't know if they are true or not.

Axar.az presents 5 conspiracy theories which turned out to be true:

1. Tuskegee Syphilis experiment

This US experiment ran from 1932-1972 and involved giving nearly 400 African American men syphilis without their knowledge or consent. The men were told they had “bad blood” rather than being informed they had the STI or being treated for it.

The study aimed to see if the STI affected black men differently from white men and by the time it ended only 74 of the original participants were alive.

2. Project MK-ULTA

Wired reports this CIA programme saw agents giving unwitting human subjects drugs as a form of mind control. They also used electroshock therapy, hypnosis, subliminal persuasion and isolation techniques.

The programme is mentioned in the book The Men who Stare at Goats, which was later turned into a film starring George Clooney.

3. The Nayirah testimony

In 1990 a 15-year-old girl known as “Nayirah” gave evidence to Congress which helped spark support for the first Gulf War.

The girl claimed Iraqi soldiers had removed babies from incubators and left them to die, but this fact was later refuted by Amnesty International.

After the war the New York Times reported “Nayirah” was actually the daughter of the Kuwaiti ambassador and her testimony was arranged by a PR firm, Hill & Knowlton.

4. Operation Northwoods

This was a Cold War plan by the US government to create fake attacks in America designed to be blamed on Cuba, to drum up support for war with the Latin American communist country.

Records show it never went beyond the planning stage.

5. Operation Paperclip

This was a secret plan to bring Nazi scientists to America to work for the CIA at the end of World War II.

An account of this plan was revealed by journalist Annie Jacobsen in her bookOperation Paperclip: The Secret Intelligence Program that Brought Nazi Scientists to America.

According to Ynet, the scientists help develop chemical weapons for the US and worked alongside American scientists to develop LSD.
