Apparently, President Eisenhower’s farewell address was seen as totally nuts:
For fifty years, Americans have regarded Eisenhower’s Farewell Address with a mixture of awe and bewilderment. Speaking three nights before the end of his Presidency, in 1961, Eisenhower warned of a “scientific-technological élite” that would dominate public policy, and of a “military-industrial complex” that would claim “our toil, resources, and livelihood.”
… Some historians have regarded the Farewell Address as an afterthought, hastily composed at the end of 1960 as an adjunct to the 1961 State of the Union. Others have regarded it as the soulful expression of an aging President who was determined to warn the American people of dangers ahead. But the Moos papers make clear that the address, far from being an afterthought, was among the most deliberate speeches of Eisenhower’s Presidency. Regarded in his day as inarticulate and detached, Eisenhower in these papers is fully engaged, grappling with the language of the text and the radical questions that it raised.
