SANTA FE, N.M. (AP) - Former Soviet leader Mikhail Gorbachev decries America's military buildup since the Cold War and he is calling for more international cooperation in addressing political and environmental problems. Gorbachev says the growing U.S. defense budget is pushing other countries to do the same and he contends that the expansion of conventional weapons also will undermine efforts to abolish nuclear weapons. Gorbachev, who left office in 1991, was in Santa Fe to deliver a speech to benefit the Santa Fe Institute, a research and education center. He made his comments at a news conference before his lecture.
