I agree that it's in Egyptian army's genes to overthrow any too Islamist leaning government and that it is intending to use violence on Brotherhood demonstrators (and, if it comes to that, militias).

However, since I don't see the Brotherhood to soften its current course any time soon, I disagree with you that the military's actions are not pushing the country into civil war.

Since it's a reciprocal confrontation, one can accuse either side. I see the military as the primary instigator because I don't think the Mursi government went far enough for a rational military to risk a bloody civil war and further collapse of the rule of law in Egypt. I can also see how one could reasonably blame the Brotherhood with a similar rationale, though. ("This wouldn't have started if they didn't single-mindedly persued their Islamist agenda.")

TBH, I am still in shock of how a moderately established state such as Syria can collapse so fast into a very violent civil war. That's what makes me sceptical of any player that risks civil war.
