A good hypothetical question. Our on shore and off shore interests had experienced numerous military attacks from the mid 70's til 9/11/01. We have had no attacks on our soil since 9/11(over 5 years), and limited attacks on our direct interests(embassies, worldwide bases, diplomatic outposts etc) since then. Will we be attacked again by islmamic fanatics determined to destroy our way of life? I believe so. I also believe a winner take all world war is being waged on us, and we must stay on the offensive to win. We did it in WWII, and are not now speaking German and Japenese. I don't want to see our women wearing burkas.
The international war with terrorism is ongoing. You have 3 choices in fighting it-Take the offensive, take the defensive, or do nothing at all and LOOSE. At this time in history it appears the ignorant masses don't have the guts to do anything, so are choosing for us to loose.
