From The Sunday Times:
Adolf Hitler’s glee at exploiting the 1936 Berlin Olympics as a showcase for Nazism turned to fury when the black American athlete Jesse Owens won four gold medals. The Chinese leadership must by now be wondering whether staging the Games in Beijing will bring the regime more accolades than brickbats. Be careful what you wish for, as Confucius probably said.
In defence of the Olympic movement, Berlin had been selected before the Nazis came to power. No such excuse covers the decision to award the coveted prize to Beijing. In 1989 the Chinese government crushed the peaceful protests in Tiananmen Square as the world looked on in horror. China still secured the Olympics and a propaganda triumph and has looked forward to showing off to the world.
The authorities must have reflected that other governments are rarely brave enough to boycott the Olympics. The Berlin Games proceeded even though the Nazis had by then implemented the infamous Nuremberg laws that deprived German Jews of basic human rights.
