トルーマン・ドクトリン
Buffett was a vocal critic of the Truman Doctrine and the Marshall Plan. Of the Truman Doctrine, he said: "Our Christian ideals cannot be exported to other lands by dollars and guns." Buffett was also "one of the major voices in Congress opposed to the Korean adventure," and "was convinced that the United States was largely responsible for the eruption of conflict in Korea; for the rest of his life he tried unsuccessfully to get the Senate Armed Services Committee to declassify the testimony of CIA head Admiral Roscoe H. Hillenkoetter, which Buffett told [Rothbard] established American responsibility for the Korean outbreak."
