The late 1960s and early 1970s saw a general thawing of U.S.-Soviet relations, ushering in a hopeful era of nuclear arms control, which became most apparent in the Strategic Arms Limitation Talks, or SALT.
The two sides forged a pair of groundbreaking agreements in 1972: the Anti-Ballistic Missile (ABM) Treaty limited the countries’ deployment of missile defense systems to their national capital and one ICBM site, and SALT I, which restricted their number of nuclear missile silos and submarine-launched missile tubes for a five-year period.
SALT I did not address strategic bombers or warhead arsenals.
