Pulling off an Egypt in my Country would be an Uphill Task

Many reasons will be cited to explain the success of what has been dubbed "the Egyptian Revolution". (By the way I am still curious to know whether Prof Levitsky would categorize this as a revolution.) For me, though, this pictures here capture the reason the uprising went as it did and why it cannot be replicated in many countries South or West of Egypt.

Protesters shake hands with soldiers

Nowhere in Sub-Saharan region do you find such a relationship of neutrality between the military and the people. It is either the military ousts an incumbent government in a coup or the incumbent government uses the military to stave off an uprising. In either case you expect a lot of blood and little departure from political and economic status quo.
It is therefore only sensible to treat Egypt as a unique case which cannot be scaled up to other countries facing similar political woes, given heterogeneity of conditions in those countries. Instead, I would interest myself in establishing whether Egypt's military relations with the US, domestic institutions, culture and/or religion could be cited to explain why the military practiced such restraint.
