The hell of it is that it is costing thousands of lives, and will cost many more until the terror masters are destroyed, or we surrender
Michael Ledeen:
Our main enemy, the single greatest engine in support of the terror war against us, whether Sunni or Shiite, jihadi, or secular, Arab or British or Italian or Spaniard, is Iran. There is no escape from this fact. The only questions are how long it will take us to face it, how effective we will be when we finally decide to act, and how terrible the price will be for our long delay. (Link)
