How did this happen? To blame a particular president, a particular administration, or a particular agency simply will not do. The abuses described in the report prepared by the Senate Committee on Intelligence did not come out of nowhere. Rather than new, they merely represent variations on an existing theme.
Since at least 1940, when serious preparations for entry into World War II began, the United States has been more or less continually engaged in actual war or in semi-war, intensively girding itself for the next active engagement, assumed to lie just around the corner. The imperatives of national security, always said to be in peril, have taken precedence over all other considerations. In effect, war and the preparation for war have become perpetual. [ . . . ]
One consequence of our engagement in permanent war has been to induce massive distortions, affecting [the] apparatus of government, the nation, and the relationship between the two. The size, scope, and prerogatives accorded to the so-called intelligence community — along with the abuses detailed in the Senate report — provide only one example of the result. But so too is the popular deference accorded to those who claim to know exactly what national security requires, even as they evade responsibility for the last disaster to which expert advice gave rise.
