I fail to understand your point.
1) I stated they do not fear death. I assume you are agreeing with me?
2) Explain how fear of not reaching paradise can be exploited if Mecca is bombed (or threatened danger). In such an instance, according to the twisted belief of the extremist, this would result in the promised paradise. Whereas Refusing to sentence them all to an early death and Global Jihad by virtue of releasing atomic weaponry to carpet the Middle east, would result in denial of their dream of numerous virgens in heaven.
Hardcore Muslims are required to visit Mecca once in their life. If the rock is destroyed, their requirement can't be fulfilled. If we defile their corpses with some unclean pig blood, they can't reach paradise. That is their weakness.
