I haven`t heard much "happy talk" about our dying soldiers.
If we don`t defend our freedoms "over there",..then we will soon be defending them "over here".  Which would you prefer?
It`s best we fight them in the sand boxes they hide in, no matter where they find safe haven (ie Pakistan..where we got BinLaden). If we give them quarter and we retreat into our "fortress between two oceans", then they will soon be among us in numbers, through our porous borders, after having recruited and regrouped and trained young "Madrassa" graduates into more of their ilk. 
You can`t always pick the place and time of your fight.. when you can, it`s to your advantage. Just my old two cents.
