Placing Sept 11 in historical context

Over the weekend there was an interesting op-ed in the New York Times by Joseph J. Ellis, Finding a Place for 9/11 in American History. First he questions the threat of September 11 to national security, "in the grand sweep of American history" and finds, "it does not make the top tier of the list." And as such, he questions whether the broad changes to domestic and foreign made in its name are justified. Second, he examines when such changes have been made (e.g. 1789's Alien and Sedition Acts and the internment of Japanese-Americans during WWII) and finds:

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.

It's ridiculous that in the effort to "win" the war on terror, we're scraping the constitutional protections that make America the great country that it is. And as Professor Ellis writes, history will likely show that once again, we've overreacted.
