The publication of the Pentagon Papers shattered the post-World War II complacency of the United States and its reputation as the “good guys” in its struggle against the totalitarian Communist dictatorship of the Soviet Union.

It was a 7,000 pages of historical study of the development of the war that revealed that three presidents and their administrations – of Kennedy, Johnson and Nixon – had lied to the public about In the late 1960s, the United States was still in the victory trance of World War II. America and its allies had not only defeated the murderous regime of Hitler in Nazi Germany and liberated the death camps, but also it had established a new world order with the United Nations, the Geneva Conventions, the transatlantic defense pact of NATO and finance agencies like the World Bank and International Monetary Fund.

Since the U.S. was seen as  the dominant word power defending democracy against the totalitarian society of Stain’s Soviet Union, its “mistakes” and “excesses” were largely excused or overlooked. Most of the American public was unaware of, or sympathized with, the American overthrow of at least 11 to 14 foreign governments with as many as 70 attempts as part of the “Cold War” with the Soviet Union.

He was 92.
