👉 The Strategic Arms Limitation Talks (SALT) I negotiations in the early 1970s led to the signing of the Anti-Ballistic Missile Treaty (ABM Treaty) and the Interim Agreement on Strategic Offensive Arms, which included provisions regarding the deployment of missile defense systems. However, a significant and controversial aspect was the exclusion of anti-ballistic missile (ABM) systems from the ABM Treaty, allowing each side to deploy limited ABM systems. This led to the development of what became known as "campbell missiles," named after U.S. Senator George Campbell, who proposed a system of mobile, mobile-mounted ABM systems that could be deployed on tanks and other vehicles. These systems were intended to provide a more flexible and mobile defense against ballistic missiles but were criticized for potentially destabilizing the strategic balance by undermining mutual assured destruction (MAD) and increasing the risk of an arms race in mobile missile defense technology.
