The United States should again become a leader in arms control and disarmament and ratify a global test ban treaty to encourage other nuclear powers to do so, the former head of the U.N. weapons inspection team said Saturday. "U.S. ratification of a comprehensive test ban treaty would be likely to have a positive domino effect on China, India, Pakistan, Iran, Iraq and Israel," said Hans Blix, who retired last year as the head of UNMOVIC, the U.N. agency that conducted the inconclusive search for chemical and biological weapons in Iraq before the U.S.-led invasion. "It would make the development of new types of nuclear weapons much more difficult," Blix told a two-day conference on India's growing political and economic role in the world.
