It happened today - January 13, 2016
Never walk out of a voting body in a huff. Never. I know it can seem tempting. But history doesn't encourage the practice. For instance, on Jan. 13 1950 the Soviets stormed out of the UN Security Council because it wouldn't unseat "Nationalist China" (Chiang Kai-shek's regime holed up in Taiwan) for the Communist kind run by Mao Zedong from Beijing in, well, actual China.
