John on S C.
The officers of the Egyptian military are members of the educated class, at least in part. Something of a tradition from the days when the British ran the upper levels of the government. I wouldn't be surprised if the families controlled some businesses.
(They want stability, but does this necessarily mean support for Mubarek? They could be seeing the handwriting on the wall. Dunno).

Why do so many left-leaners take it out on Hillary? She doesn't make policy; Obama and his advisors do that and she carries it out. Of course if she had been nominated in the primary and won, then she would be responsible. Obama seems to be following the path set down by Bush and his predecessors. Listen to Obama's comments on the situation.
Background-
The U. S. started paying Egypt $2 billion/year starting in 1979 and Obama and Congress have done nothing to change the balance from 65 percent to the military to something better for the people. Only $35 million of that goes toward education.
