Feeeaaaarrr! FFFEEEEEAAAAAAARRRRRR!!!!
They're in every state! Watch out! There might be one just around that corner! See all the sirens? Oh, wait, it's just another husband who shot his wife and kids, no big deal, no problem as long as it's just us Real Americans killing thousands of us, and not THEM killing tens of us!
And if "there's terrorists in every state" is your way of saying the war against terrorism isn't won, heck, by that standard, the war against Nazism still isn't won. Neither is the Cold War. For that matter, there's still people who keep slaves - yes, there are - so by your standard, the war against slavery ain't done yet. The key is, you can't win a war against an idea, against a freaking word. No matter how stupid or evil an idea is, there's ALWAYS going to be some idiots who follow that idea...and the more attention is given to these idiots, the more like-minded idiots will be drawn to them - more than anything, they need publicity...and sympathy. All the Real-American He-Man We-Bomb-ISIS-all-day-all-the-time machismo will never - repeat, NEVER - "get rid" of terrorism or any other kind of 'ism'.
So get over yourself, and your side's misguided sense of leadership-by-testosterone.
