Containment

node

The organising American strategic idea of the period, and one whose author spent the rest of his life objecting to how it was applied. George Kennan, then charge d'affaires at the US embassy in Moscow, set it out in a long cable in February 1946 and in an anonymous article signed "X" in Foreign Affairs in July 1947: Soviet hostility was structural rather than responsive, it was not amenable to negotiation, but it was patient and cautious, and could therefore be met by "long-term, patient but firm and vigilant containment" until it changed from within. Kennan meant something selective and largely political and economic — hold the few industrial regions that mattered, rebuild them, and wait. What was built on it was global and largely military: alliances on every continent, a permanent peacetime mobilisation costed in NSC-68, and intervention in places Kennan regarded as strategically marginal. The gap between the idea and its implementation is one of the genuinely useful analytical threads through the whole forty-five years.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
