Khandro - //To behead an elderly priest, and injure and terrorise old women in the belief that you will, if shot, go straight to heaven, and it may be comforting to think that you have 70 virgins waiting for you. But you might think again if it automatically triggered the loss of all benefits for your parents and family members, and their dispossession (applies to home-grown terrorists only) of their homes, - the robust response of the Israelis. //
Your premise requires a rational mind that thinks outside itself, reasons, and cares for anyone else on the planet - none of which are the mind set of the common-or-garden terrorist.
