Answer:
To defeat the Soviet Union once and for all.
Step-by-step explanation:
Reagan said he wanted his legacy to be "to defeat the Soviet Union once and for all."
This is evident in what was known as Reagan's Doctrine. The doctrine is established on the needs of the United States to decrease the Soviet Union influence around the world, particularly in Eastern Europe, the middle east, Africa, Asia, and Latin America. This is believed to the main strategy of the United States to win the Cold War against the Soviet Union once and for all.
