The uncertainty about whether atomic weapons will be used in future war, whether local or general, lends itself to political exploitation in the cold war. The efficiency of nuclear weapons in wartime, and their resulting threat-value in either war- or peacetime, constitute their political-military worth. In peacetime, the threat-value of weapons can be exploited in many ways: by an ultimatum, by authoritative or inspired statements on capabilities or intentions, by studied disclosures of new weapons at ceremonial occasions, by means of maneuvers, redeployments of forces, or by so-called demonstrations.
