The arabs play a game that Israel cannot, and that is the game of public relations. They can always strike from a position of inferiority, they can always make themselves out to be the down-trodden, the weak, the innocent fighting off the well-equipped aggressor--even when they sneak around and initiate the fighting. Israel must either take it and do nothing, or fight back and face criticism. A few photos of Palestinian shanty-towns and you get hordes of neo-hippies singing cumbaya for the poor little suicide bombers.
It's the same game the US plays, and with the same outcome. If it wasn't for the United European/Scandinavian Emirates pointing their collective finger and screaming Zionist, or the hordes of Northern Californian Armpit-braiders with their Israel = Hitler bumper stickers, this habit of grasping at global sympathy would have been silenced long ago.
