We face a hostile ideology — global in scope, ... ruthless in purpose, and insidious in method. Unhappily the danger it poses promises to be of indefinite duration.

Only thus shall we remain, despite every provocation, on our charted course toward permanent peace and human betterment. —President Dwight D. Eisenhower, 1961, in his speech warning of the rise of the military-industrial complex
