Context matters.

Reactions to active conflict have a different threshold than normal civil operations. The interests of the US are biased towards continued peace. War is inherently value destructive (even if the military industrial complex gets to sell more stuff for a bit) so a majority of the population from a multitude of perspectives would rather remain fat and happy with their circuses (sports-ball).

That balance changes, as it has since the dawn of western history times, when outside forces disrupt the regular machinations of the people. When events like Pearl Harbor, the turn of the century terrorist airplane hijackings that turned them into missiles and America's citizens into hostages to our own national security theater paranoia, or some country turning the place all of our iPhone and computer brains are fabricated in into a war zone.
