Henry Kissinger prägte in den siebziger Jahren als Sicherheitsberater und Außenminister entscheidend die amerikanische Außenpolitik.

Deterrence is not the sole purpose of nuclear weapons. If nuclear weapons are to be useful, they must also be useable. If they cannot be used, they are not a credible deterrent. This inevitably turns nuclear weapons into weapons of warfare. Smaller nuclear weapons make deterrence more credible, but also make their use more likely.
