On November 17, 1969, after a three-year delay, the United States and the Soviet Union initiated Strategic Arms Limitation Talks (SALT). Involving strategic systems and policies vital to the security of both superpowers, their allies, and the world, these talks have the potential of becoming the most important series of United States-Soviet negotiations since World War II. They can affect not only the military-technical aspects of the strategic balance but United States-Soviet political relations and the future role of nuclear weapons. Given the complexity and sensitivity of the subject, it is not surprising that negotiations are still continuing. Even if an early, limited agreement is reached, SALT meetings can be expected to span a period of many years.
