Lebanon is a good model for what I’m worried will happen in Egypt. The Lebanese revolted to throw Syria out of their country, but the end result was essentially a Hezbollah takeover.
In Egypt, even if the majority of the protesters genuinely want democracy (which may well be the case), the Muslim Brotherhood will probably be able to use the chaos for their own ends. Jihadist movements are very good at co-opting rebellions that were originally based on secular grievances. In a lot of ways, it’s similar to what fascist and communist movements were able to do in the last century.
You’re right. They will suffer the same fate as Lebanon if they allow this type of cancer into their governing process.
