Not yet , I am only speculating, but I see a pattern.
The protesters are very appealing to the population and the army is reluctant to fire on them, but their demands are stronger than the government can give and survive , there is no central figure to negotiate with , the protests will continue untill the government lashes out.
Teinanmien Square broke my heart , I would be very pleased to be totally wrong, but how can the Egyption government give only half and survive? Who would accept the half?
