It is. When weather gets colder and harsher there will be more of Bin Ladens troops seaking shelter in the warm caves. Me thinks it would be more productive to let the most of them gather in one place than trying to locate 5 here 10 there, etc. All though it would be very demoralizing to knock off a few groups in areas that the ragheads think are very secure. I have no doubt that there are Seal Teams with a sniper or two amongst them watching some key groups as we sit typing on our keyboards.
I would wager, if the truth were known, that there are small groups of dead Bin Ladenites scattered about the country side right now.
