Overview
When I talk about how our government does human experimentation and crimes against humanity with impunity, acknowledged factual information such as this is part of the cookie crumb trail, that leads to the Roswell and MK Ultra operations.
General Shiro Ishii
There was a figure named Shiro Ishii, who was a Japanese microbiologist and army medical officer with the rank of Surgeon General (equivalent to a Lieutenant General). He was the director of Unit 731, a biological warfare unit of the Imperial Japanese Army.
Unit 731 was a secret and highly funded program based in Japanese-occupied Manchuria (China). Under Ishii’s leadership, the unit conducted horrific and lethal human experiments on prisoners of war and civilians, primarily Chinese, but also Russians and others. The purpose of these experiments was to develop and test biological and chemical weapons.
The atrocities committed by Unit 731 included:
- Infecting prisoners with deadly pathogens like plague, anthrax, cholera, and typhoid.
- Conducting vivisections (dissection of live subjects), often without anesthesia, to observe the effects of diseases on internal organs.
- Testing the effects of toxins, gases, and extreme temperatures on human subjects.
- Field-testing biological weapons on civilian populations, such as by dropping plague-infected fleas from aircraft or contaminating water sources.
The biological weapons developed by Unit 731 are estimated to have killed tens, if not hundreds, of thousands of people in China.
Following the end of WWII, Ishii and other leaders of Unit 731 were granted immunity from war crimes prosecution by the United States government in exchange for the vast amount of data and research they had collected from their experiments. This information was then used to benefit the U.S. biological warfare program.
SShiro Ishii was granted freedom and was never prosecuted for his war crimes. After World War II, the United States offered him and other key members of Unit 731 immunity from prosecution at the Tokyo War Crimes Tribunal.
This deal was made in exchange for the vast amount of data and research they had collected from their horrific human experiments. The U.S. government, particularly its biological warfare program at Fort Detrick, considered this information “absolutely invaluable” and believed it could not have been obtained in the United States due to ethical constraints.
As a result, Ishii lived a free life in Japan, unpunished for the atrocities he directed. He died of laryngeal cancer in 1959. The U.S. government’s decision to grant immunity to the leaders of Unit 731 in exchange for their research has been a source of significant controversy and criticism ever since”
