Recent emphasis in arms control has centered upon the control of the arms race and the prevention of nuclear war. These objectives are obviously interrelated, as some weapons deployments and strategic attitudes present more of a threat than others to the goal of avoiding nuclear or large-scale conventional warfare. Some features of the arms race have even been consistent with overall prevention goals. Particularly where international tension has a strong ideological component, adversaries premise their security on possessing sufficient unilateral capabilities to inflict unacceptable damage and on being perceived as having the will and capability to do so. As ideological tensions wane or disappear, technical considerations grow more prominent, and actual and potential weapons capabilities are viewed in more interactive and even cooperative fashion. During the Nixon–Ford–Brezhnev tenure, bipolar relations have become generally more cooperative, and this development has certainly been reflected in a continuing search for bipolar arms-control agreements. But, at the same time, bipolarity has also been significantly eroded and even superseded by emergent multipolarity and interdependence in such domains as trade, money, and natural resources.
