North Korea defiance challenges moral authority of nuclear club

When North Korea claimed triumphantly that it had tested its first hydrogen bomb, it was roundly and predictably condemned by the United States, China, Russia, Britain, France and India, countries estimated to possess a combined total of more than 15,000 nuclear warheads.
Non-nuclear powers condemned the test, too, including Japan, the country that was on the receiving end of the only atomic bomb attack in history — the U.S. bombing that ended World War II in the Pacific in 1945.
