"When Japan surrendered, the US was faced with a choice: Either disarm, as we had done in the past, and enjoy the prosperity that comes from releasing so much wealth and energy to the private sector, or maintain ourselves on a full military basis, which would mean tight control not only of our allies and such conquered provinces such as West Germany, Italy, and Japan but over economic–which is to say political–lives of American people. As Charles E. Wilson, a businessman and politician of the day, said as early as 1944, “Instead of looking to disarmament and unpreparedness as a safeguard against a war, a thoroughly discredited doctrine, let us try the opposite: full preparedness according to a continuing plan.”

The accidental president, Harry Truman, bought this notion. Although Truman campaigned in 1948 as an heir to Roosevelt’s New Deal, he had a “continuing plan”. Henry Wallace was onto it, as early as: “Yesterday, March 12, 1947, marked a turning point in American history … Yesterday, President Truman proposed, in effect, America police Russia’s every border. There is no regime too reactionary for us provided it stands in Russia’s expansionist path. There is no country too remote to serve as the scene of contest which may widen until it become a world war.” But how to impose this? The Republican leadership did not like the state to be the master of the country’s economic life while, of the Democrats, only a few geopoliticians, like Dean Acheson, found thrilling the prospect of a military state, to be justified in the name of a holy war against something called communism in general and Russia in particular. The fact that the Soviet Union was no military or economic threat to us was immaterial. It must be made to appear threatening so the continuing plan could be set in motion in order to create the National Security State in which we have been living for the last forty years.

What is the National Security State? Well, it began, officially, with the National Security Act of 1947; it was implemented in January 1950 when the National Security Council produced a blueprint for a new kind of country, unlike anything the United States had ever known before. This document, known as the NSC-68 for short, and declassified only in 1975, committed–and still, fitfully, commits–us to the following program: First, never negotiate, ever, with Russia. This could not continue forever; but the obligatory bad faith of US-USSR meetings still serves the continuing plan. Second, develop the hydrogen bomb so that when the Russians finally develop an atomic bomb we will still not have to deal with the enemy without which the National Security State cannot exist. Third, rapidly build up conventional forces. Fourth, put through a large increase in taxes to pay for all this. Fifth, mobilize the entire American society to fight the terrible specter of communism. Sixth, set up a strong alliance system, directed by the United States (this became NATO). Seventh, make the people of Russia our allies, through propaganda and CIA derring-do, in this holy adventure–hence the justification for all sorts of secret services that are in no way responsible to the Congress that funds them, and so in violation of the old Constitution.

Needless to say, the blueprint, the continuing plan, was not only openly discussed at the time. But, one by one, the major political players of the two parties came around. Senator Arthur Vandenburg, Republican, told Truman that if he really wanted all those weapons and all those high taxes to pay for them, he had better “scare hell out of the American people.” Truman obliged, with a series of speeches beginning October 23, 1947, about the Red Menace endangering France and Italy; he also instituted loyalty oaths for federal employees; and his attorney general (December 4, 1947) published a list of dissident organizations. The climate of fear has been maintained, more or less zealously, by Truman’s successors, with the brief exception of Dwight Eisenhower, who in a belated fit of conscience at the end of his presidency warned us against the military-industrial complex that had, by then, established permanent control over the state."

The entire essay, along with many of Vidal's other writings is highly recommended.
