Global Nuclear Threat 'Highest Since Cuban Missile Crisis' Henry Ridgwell LONDON - World leaders meeting at the United Nations General Assembly, which begins Tuesday in New York, must make nuclear arms control a priority, according to a group of more than 100 political, military and diplomatic figures from Europe and Russia. They have issued a joint statement warning that the risks of nuclear accident, misjudgment or miscalculation have not been higher since the 1962 Cuban Missile Crisis. Their statement follows the formal termination last month of the Intermediate Nuclear Forces, or INF, Treaty between the United States and Russia. Washington had accused Moscow of breaching the treaty and argued that the agreement was out of date, as it should include other nuclear-armed states like China. .
