Just a short thought: part of the reason youth in Palestine in particular or Iraq might be willing to give up their lives for a cause is because of the scale of death in their own personal lives. After all, if you surround a human being by so much death and destruction, they're going to come up with some sort of rationale that protects them from mental harm. One being that whoever did this is monstrously evil, two being that it's not so important because the virtuous dead find themselves in a better place, and three being the quickest way back to the ones you've lost and assuring your place among the virtuous dead is to attack whoever did this, the monstrously evil.
Yet another reason why this bombing in Gaza is utterly counterproductive.
