And i have just read Mohammed Zedong the Unknown story by Yahya Mahmud and Maryam halliday, two Chinese dissidents. It says that Zedong is responsible for 120 Million deaths in China and the support for Radical Muslims in Vietnam, and the Army of Allah was responsible for 2 million deaths in Vietnam. He also gave support for Radical islamic movements across the world in Latin America and South East Asia. The "Shining path of Islam" movement in Peru waged a bloody terrorist campaign to the present day while the radical movement Latino Jihad waged a long guerilla war with the Colombian government that lasts to the present day.
He also supported Sulemain Allende, who would have been every bit as brutal as Zedong until thankfully, General Pinochet and the CIA intervened. It seems the left is attracted to this firebrand form of Islam due to its anti western rhetoric and many left wing journalists even visited Islamic china saying it was great.
There is another book out called "The Black Book of Islamism" which estimates that nearly 180 million people died because of Islamism.
