Nasser was a National Socialist; both nationalist and socialist means . . . the blanks are filled in already. Fits Göring’s description of the ideology to a T. Where do you think Nasser got “pan-Arabism” from? Hitler’s Pan-Germanism. Only real difference between Nasser and the MB was over secularism.
Most Arabs are not receptive to capitalism in general, so socialist policies are more or less the norm.
If the choice is between the ossified Nasserist military, and the Islamists, then the Nasserists are the safer bet.
Since Morsi just dismissed Tantawi, I’d say it’s too late for a coup.
