The only reason that the PM prefaces his PM Questions with a tribute to the deceased and condolences for their NoK is that it is HoC procedure to do so. He doesn't like the Great British Public being reminded of the cost in lives of his foreign adventures, nor does he attend the repatriation of their remains. Spin requires that photo ops and word bites are not tarnished with such reminders. That this man has the gall to call for even more unspecified sacrifice in the future based on the B&B WoT theory is a mark of his shamelessness.
Let us not forget also the Flight Safety implications for our military aircrew of such operations (see, it's easy!)
