"The experience of a 'détente' in American-Soviet relations in the 1970s ultimately failed for a number of reasons,including an underlying difference in conceptions of détente: The American leaders saw it (in Kissinger's words) as a way of 'managing the emergence of Soviet power' into world politics in an age of nuclear parity;the Soviet leaders,for their part,envisaged it as a way of managing the transition of the United States from its former superiority into a more modest role in world politics… Ultimately disillusionment affected the leaderships on both sides… and the détente commitment was not only devalued but used as the basis for additional hostile charges against the other side."
Raymond L.Garthoff,"Détente and Confrontation: American-Soviet Relations from Nixon to Reagan," 1982
