I think that as for Benghazi site concerns soldiers here just went home if not joining uprising as most military units in eastern Libya.

Anyway I see the biggest problems with these "secular" dictatorship in economy. I know something more about Egypt but system is similar also to other these countries. Basic problem is that ruling group did not allow existence of any independent economic companies and at the same time they divide between themselfs all economic spheres so they are not rivals to each others. So in reality it looks like this: there is only one factory in whole Egypt which produce refrigerators - because of domestic production run by people close to regime (this will probably change now) any import of foreign refrigeratos is meet with extremely high import tarrifs (like 100% or similar). And because this producer have no rivals he did not care about quality or about low prices - one econom here described their products to be on level as in socialist Czechoslovakia in 1970s!!! However ordinary people here can see how people live in Europe and this creates similar effect to what was in communist block in 1980s - people want much higher standard of living than that corrupt system is able to provide so people riots.
