This Hamas guy, Yassin I think was his name, deserved to die but I'm pretty sure that killing him won't really make much of a difference and of course will only add to the violence. I guess if one day Osama grows to be old, people will say ah, he's old, why bother. Of course, at the rate we are going, Osama might just die of old age.
Also, it kinda funny yet it's not, but I think I saw that when I.D.D. got Yassin with a helicopter gunship, all that was left was a big grease spot and and some scrap metal from his wheel chair. I guess he should have had some better body guard protection or maybe a faster wheel chair.
