I understand that most of us are running high on complex emotions as we are witnessing something unprecedented. We shall serve the justice when time comes, but c'mon we are not doing another holocaust!
I do think so. I just read that police in Egypt (one of Israel closest ally) randomly killed 8 Israeli tourists. This shows while the upper up of many Arab countries are more receptive of Israel, the masses simply don't.
As I said, the likely reason why this anger is not poured against a people only 9 million in size, is because the U.S is protecting this state, the cost-benefit ratio doesn't prefer a long war of annihilation .
Once the U.S is out you will see what people really crave, not only in the Middle Eastern region but as far away as most of the muslim majority countries.
Without the U.S meddling we will see this Middle Eastern region rife with conflicts with states going to war with each other for control and consolidation. And once the winner comes out on top, what better way to rally people and seek legitimation other than the second conquest of Jerusalem ?
And what better way to keep spirit high other than the constant reminder that the Israelites has committed crimes their kin in race and religion ? I could already envisioned what kind of state sponsored vilification once the time comes.
