historicalpoliticalacademic

A strategic foreign policy aimed at preventing the expansion of a hostile power or ideology.

Unlike direct military invasion or total destruction, containment uses alliances, economic pressure, and military deterrence to keep an adversary within existing boundaries.

The story behind the word. From Latin 'com-' (together) and 'tenere' (to hold), 'containment' originally meant holding physical contents inside a box. In 1947, diplomat George F. Kennan, writing as 'X' in Foreign Affairs magazine, adapted the term into the premier American strategy of the Cold War, urging 'a long-term, patient but firm and vigilant containment of Russian expansive tendencies'.
