I don't think most mainland Chinese have any idea that the communist party of China under Mao, (Which still rules there.), killed some
60 million of their brother Chinese and was responsible for the worst mass murder in all of human history.
You mean the Saddam who invaded his neighbours? Who's army he sent in an invasion of Kuwait that he raped and pillaged? The Saddam who dropped poison gas on his own people? The one who fed his enemies feet first into wood-chippers? Who massacred Kurds and Shias? The one who fired on United Nations forces after he signed a cease fire? You mean the Gaddafi who's embassy staff shot and killed a British policewoman? The Gaddafi who exterminated any who questioned his rule? The Gaddafi who blew an American airliner full of college kids out of the sky, 270 dead in all? Who later blew a French airliner with 107 innocent passengers out of the sky? Who attacked his Muslim neighbour states of Chad and Egypt and plotted the assassination of other Arab leaders in the Middle East?
Yah, I don't think America defamed them. They did that to themselves by their actions, all on their own.
