The War on Trepidation

 "Terror"

1 : a state of intense or overwhelming fear overcome by terror people fleeing the scene in terror He lived in terror of being caught. ...  Merriam-Webster

Early in the so-called "War on Terror", it was pointed out that "the terrorists had won" because everything we did to fight "terror" only made us more terrified.  The more we fought terror, the more we felt that these terrible things were going to happen to us, personally, specifically, me, real soon.  The War on Terror made us terrified, and we tried to allay that fear by killing or "neutralizing" anything or anyone who made us afraid.

Like a fear of spiders or snakes or sharks, the fear does not go away simply by killing one of them; there are always more.  The only way we might stop fearing these creatures is by making them extinct -- we no longer fear the tyrannosaurus rex because it is extinct.

The problem with "The War on Terror" is that the terror we are warring on is us; and so the only way to end that war is by making us extinct.

... unless we can come up with another way to deal with our "intense and overwhelming fear" of each other.
