Military flight barnstorms N. Shore, Why are we so jittery?

uneccessarily jittery by my standards. If it was anything other than a planned barnstorming, what would you, or could you have done differently. The terrorists have us doing exactly what they want....shaking at every thunderclap, thinking its an attack at every turn. A car backfires and everyone goes into a panic, a manhole cover blows and its an attack, a trash track fire happens and everyone thinks they've been gassed. Yes we should have preparations and plans in place but the bottom line is that when a real attack is imminent you wont have a clue that it is coming or in what form. Better to live life trusting in God and enjoying every breath you take...don't let down your guard, but enjoy more and jump less.
