Why did relations with the soviet union get worse when carter was peresident?

Answer 1

Carter was also confronted with major challenges over which he had little control, although he was criticized for lurching between weak and hard‐line policies. Soviet intervention in Cuba and the Horn of Africa and Russian military occupation of Afghanistan led the administration to support a military buildup. Carter ended his opposition to increases in the military budget, approved construction of the MX missile, abandoned his SALT II Treaty, canceled U.S. participation in the Summer Olympics in Moscow, and resumed compulsory draft registration. In the "Carter Doctrine," he pledged protection of the oil‐rich Persian Gulf region and established a rapid deployment force to enforce it.
