Do you thinks perhaps Israel agreed to this truce in order to not deplete its resources for a bigger conflict eg Iran, hezballah?
The truth is, if Israel showed might and no mercy in Gaza even with the civilians and eradicated them, it would not draw enemies into a conflict. Rather, enemies of Israel would go the opposite way and fear Israel. That's how Gd works with us Jews. When we show strength, the world will respect us more. This generation lacks guts and faith in Hashem, in my opinion.
