How does the relationship between the us and the soviet union evolve during the 1970's?

During the 1970s, the relationship between the U.S. and the Soviet Union saw a mix of tension and détente. This period was marked by significant arms control agreements, such as the Strategic Arms Limitation Talks (SALT I) in 1972, which aimed to curb the nuclear arms race. However, underlying tensions persisted due to ideological differences and conflicts in various parts of the world, culminating in events like the Soviet invasion of Afghanistan in 1979, which strained relations and effectively ended the détente era.
