The 2012 Olympics one minute of silence campaign refers to an international campaign created to persuade the International Olympic Committee (IOC) to hold one minute of silence at the opening ceremony of the 2012 London Olympics to remember the Israeli athletes killed in the Munich massacre at the 1972 Olympics by the Palestinian terrorist organization Black September. Support for the campaign came from a number of high-ranking officials and governments, including the United States Congress, U.S. President Barack Obama, U.S. Secretary of State Hillary Clinton, U.S. Republican Party presidential candidate Mitt Romney, the Italian Parliament, the Australian Parliament, the Canadian Parliament, the German Parliament, and German Foreign Minister Guido Westerwelle.
