In Egypt, the Muslim Brotherhood govt would have,and was, losing legitimacy and support off its own back and would have fallen without needing to be pushed by the army, which has only served to push MBs support firmly back behind it and defacto firmly against any potentially revolutionary trend that could have developed from within the opposition.
MBs support is strongest amongst the urban poor. These people are now not just politically disenfranchised, but legally de-legitimized. Their only recourse is violence. The military putsch has made revolution harder, not easier; the masses are more divided, not less.
And crucially, what of the US troops in Egypt? Moved in barely a fortnight before the 4th of July coup? I keep coming back to this because I think it is central. There would have been no coup without a nod from the US. The US forces were moved there to secure strategic points if (when) the country slips into chaos as a result of this.
I think those that frame the military within the context of the Nasserist revolution minsunderstand the class nature of the state that movement established. It was not a workers and peasants state as in Russia or China, it was a national-revolutionary state, ie a state of the national bourgoisie. The army is the army of that state, and it represents the class interests of that state. As Nasserism gave way to Sadat and Mubarak, the state did not need to be replaced because the same class controlled it, just a different trend within that class, the comrpador bourgeoisie over time took over from the national-bourgeoisie. 40 years on, the state is not Nasserist, it is Mubarakist. And its military and security forces defends Mubarakist (ie comprador) interests, even at the expense of Mubarak himself (who was no loss, being on deaths door).
Am I misremebering when I say that the Egyptian military receives more funding from the US than any military in the region bar Israel? That itself should be enough to demonstrate that the military, under it's current leadership, is about as inclined towards revolutionary anti-imperialism as Israels is! He who pays the piper and all that...
That is not to say that there are no progressive/Nasserist elements in the military. But if there are, they are keeping very quiet. And by pushing the MB into militant opposition, the Mubarakist/imperialists are forcing potential secular-revolutionary/
If the people will no longer accept being ruled in the old way, and the ruling class can no longer rule in the old way, then stirring sectarianism, division, violence and instability amongst the people, is preferable to those who do rule, than is the prospect of facing a people uniting for revolution.
So for those anti-imperialists getting themselves worked up about the last week in Egypt, it is usually a good rule of thumb that when it comes to analysis of international political developments, if you suddenly find yourself backing the same team as both the SWP/ISO and Tony Blair, its probably well worth considering retracing your steps and figuring out just where you took that wrong turn...
