1971 Bangladesh atrocities
People disagree about how many people died.  According to the Heritage Foundation's Asian Studies Center, it could have been as few as 500,000 or as many as 3 million. It was during the Cold War and so different groups said more or fewer people had died depending on their own political ideas and goals. The Soviets, who supported Bangladesh, said that it was 3 million. The CIA said it was 200,000. Pakistan was then an ally of the United States, and the West Pakistani soldiers used weapons given by the Americans. India, which was also pro-Soviet, and Bangladesh state that nearly 3 million had been killed.
