Insanely brave could be an accurate description of Japanese kamikaze pilots, who flew through withering tripleA to hit legitimate military targets... not these people. These people commandeered unarmed airplanes and flew them into undefended targets, only one of which could be described as military. The World Trade Center Towers never fired a shot in their defense.
These acts were cowardly.
Sorry to disagree - I love your passion in this situation, and feel the same way - I hope Bush realizes this is absolutely an act of war.
The failure of any response to the USS Cole attack has, doubtlessly, emboldened these people.
