This clip is Chomsky quoting a State Dept memo, written in 1948 by George Kennan, that makes it appear as if Kennan is endorsing the US engaging on a sinister plan to maintain economic disparities between itself and other countries. Chomsky wrote this in his 1993 book What Uncle Sam Really Wants.

In fact, Chomsky omits the fact that Kennan was really arguing against the US trying to beat back communism in Asia. Kennan was really advocating letting Asia go and maintaining a sphere of influence limited to Japan and the Philippines.
