Think Doolittle Raid on Japanese mainland during WWII and the impact on morale, etc. surely, ISIS would like to have the ability to take terrorism to the front porch of an adversary.
And it will not just be a hit like 9/11 these guys want to hurt us bad. I am thinking Malls or schools. Then you will see what the Real American man is about if they hit what I just said. It is scary.
