September 11th was a powerful event in every living American's life. It was a unique experience for all of us and I certainly hope nothing more traumatic occurs in my lifetime. But, as this interesting NY Times essay
suggests, in the broad scheme of US history it will probably be viewed as much less important than it still feels.
My first question: where does Sept. 11 rank in the grand sweep of American history as a threat to national security? By my calculations it does not make the top tier of the list, which requires the threat to pose a serious challenge to the survival of the American republic.
Here is my version of the top tier: the War for Independence, where defeat meant no United States of America; the War of 1812, when the national capital was burned to the ground; the Civil War, which threatened the survival of the Union; World War II, which represented a totalitarian threat to democracy and capitalism; the cold war, most specifically the Cuban missile crisis of 1962, which made nuclear annihilation a distinct possibility.
Sept. 11 does not rise to that level of threat because, while it places lives and lifestyles at risk, it does not threaten the survival of the American republic, even though the terrorists would like us to believe so.
My second question is this: What does history tell us about our earlier responses to traumatic events?
My list of precedents for the Patriot Act and government wiretapping of American citizens would include the Alien and Sedition Acts in 1798, which allowed the federal government to close newspapers and deport foreigners during the "quasi-war" with France; the denial of habeas corpus during the Civil War, which permitted the pre-emptive arrest of suspected Southern sympathizers; the Red Scare of 1919, which emboldened the attorney general to round up leftist critics in the wake of the Russian Revolution; the internment of Japanese-Americans during World War II, which was justified on the grounds that their ancestry made them potential threats to national security; the McCarthy scare of the early 1950's, which used cold war anxieties to pursue a witch hunt against putative Communists in government, universities and the film industry.
In retrospect, none of these domestic responses to perceived national security threats looks justifiable. Every history textbook I know describes them as lamentable, excessive, even embarrassing. Some very distinguished American presidents, including John Adams, Abraham Lincoln and Franklin Roosevelt, succumbed to quite genuine and widespread popular fears. No historian or biographer has argued that these were their finest hours.
