since Morisi and the radical islamic MB sacked all the generals and replaced them with his stooges, a tactic used and implemented by obama btw, then this sounds like a full on Morsi dictatorship putsch
My friends still in Egypt (from when I had done some contract work there) told me this was another story the MSM pretty much missed or ignored. Morsi and company did attempt to sack and replace most all field-grade officers and the General Staff and was quietly told 'that is not going to happen' by the military. They did manage to replace a few officers, but it was not the full-on mass replacement the Islamists were hoping for.
Are you 100% sure they are all replaced? I know Erdogan did something like that, but he’s been in power in Turkey for more than a decade. Morsi’s only been in a year or so.
