Mr. Keeney says it is not certain that the Senate will pass the modified bill because Republican majority opposes many arms control efforts. One says Moscow may back out of the arms reduction treaty if Washington backs out of another treaty that puts sharp limits on defenses against ballistic missiles. Mr. Spring says the result could be an arms reduction treaty signed by both sides that has no impact in the real world. At the height of the Cold War, the Soviet Union and the United States each fielded about 12-thousand nuclear warheads. That would leave perhaps 25-hundred atomic weapons in each of the two arsenals.
Some newer weapons have many, many times the power of that early, crude, nuclear bombs. .
