Castel, strange statement. There's an implication that our military, or that of other NATO powers, would carpet bomb if unfettered. Once upon a time, different foe, that was true.
I don't think you'll find a group more dedicated to doing the job right than our military leaders, and it's not out of fear for their pensions.
I just hope it ends soon. I personally don't see these ISIS as really having the stomach for the fight, to die out there in the desert after growing up in France and eating at McDonalds etc. We shall see.
