From Nir Rosen, via Tom Ricks:
This is not about Islamism; this is about regional alliances. Whether it's the Muslim Brothers or the Communist Party of Egypt who takes over after Mubarak, we can be certain that the new regime will be less of a puppet and less part of the American, Saudi, and Israeli alliance in the Middle East than Mubarak was. This is what the Saudis fear, that the architecture they have carefully crafted with the Americans is crumbling -- with Iraq ruled by the hated Shiites, Fatah in Palestine a joke, Iran ascendant, the Saudi proxies in Lebanon a failure. This has nothing to do with Islamism.
