Containment
Ronald Reagan, a long-time advocate of rollback, was elected U.S. president in 1980. He took a more aggressive approach to dealings with the Soviets and believed that détente was misguided and peaceful coexistence was tantamount to surrender. When the Soviet Union invaded Afghanistan in 1979, American policymakers worried that the Soviets were making a run for control of the Persian Gulf. Throughout the 1980s, under a policy that came to be known as the Reagan Doctrine, the United States provided technical and economic assistance to the Afghan guerrillas (mujahideen) fighting against the Soviet army.

After the Cold War: The conclusion of the Cold War in 1992 marked the official end of the containment policy, but the U.S. kept its bases in the areas around Russia, such as those in Iceland, Germany, and Turkey. Much of the policy later helped influence U.S. foreign policy towards China in the 21st century.
