The awful WW2 truth Japan wants to keep secret

This video sheds light on a dark chapter in modern history. During World War II, Japan operated a top-secret biological warfare program called Unit 731, led by microbiologist Shiro Ishi. This unit carried out gruesome experiments on prisoners of war, including Chinese and Russian soldiers, as well as civilians. The experiments were designed to test the effects of various diseases and weapons on the human body. The atrocities committed by Unit 731 were kept hidden for many years, both by Japan itself and the USA which granted many of the perpetrators immunity from prosecution in exchange for their data and research.
