Understanding what happened in Gaza this summer means understanding Hezbollah in Lebanon, the rise of the Sunni jihadis in Syria and Iraq, and the long tentacles of Iran. It requires figuring out why countries like Egypt and Saudi Arabia now see themselves as closer to Israel than to Hamas. Above all, it requires us to understand what is clear to nearly everyone in the Middle East: The ascendant force in our part of the world is not democracy or modernity. It is rather an empowered strain of Islam that assumes different and sometimes conflicting forms, and that is willing to employ extreme violence in a quest to unite the region under its control and confront the West. Those who grasp this fact will be able to look around and connect the dots.
