Why was detente less successful under carter?

Détente was less successful under President Jimmy Carter due to his focus on human rights, which complicated U.S.-Soviet relations. Carter's administration criticized the Soviet Union for its human rights abuses, leading to increased tensions and a more confrontational stance. Additionally, events like the Soviet invasion of Afghanistan in 1979 further undermined détente, prompting the U.S. to adopt a more aggressive foreign policy. Overall, Carter's approach marked a shift away from the cooperative spirit that characterized earlier détente efforts.
