The Arabs could have peace tomorrow if sufficient numbers of Palestinians were not content to be used as cannon fodder in fruitless assaults on Israel even as the surrounding Arab powers distract the Arab masses with the red herring of Israel while retarding their countries with their repression and corruption.
If you know that life is basically going to be horrendously difficult at best and all but unlivable at worst or possibly even unlivable do you go on? And the choice to go on is the only thing that I think can be called hope. Because if hope isn't forced to encounter the worst possibility then it's a lie.
