Isn't the logic here that, having attained power, having had their true colors and competencies revealed, and consequent to that having been pushed from power by a coup, doesn't the logic of things dictate that the Muslim Brotherhood can never be allowed to rule in Egypt again? The bitter rivalries that would be unleashed by such a turn would be too great, but more important than that, since the MB could never trust the military again and therefore the military can never trust them again [if they ever did] then, well, like I said, doesn't logic indicate the Brotherhood is finished as a viable political force, barring of course a successful counter revolution or a total breakdown in civil order?
And doesn't it then logically follow that the Brotherhood must be aware of this reality and consequently modifies its behavior accordingly, ie becomes increasingly militant and extreme? I know some are arguing that the Brotherhood will simply go back to playing its waiting game - but I have a hard time accepting that - sure, there'll be some in the Brotherhood who will push for that approach, but I gotta believe there'll be other factions who will be making the argument that the game has irrevocably changed and the old rules are no longer relevant - which means, watch out, things could get very ugly indeed.
See it from Egyptian military's POV: with what has happened and given the bitter history between them, how could they possibly ever allow the Brotherhood back into the political process, if there even is a political process that survives current troubles? To me it seems obvious that they can't - and once you accept that fact, certain conclusions necessarily follow.
[but wouldn't that also mean that any group with Islamist inclinations must be kept subdued viz the political process? Ah... that would be my guess - which is not to suggest such an agenda would be publicly stated]
[apparently interim president Mansour is offering cabinet positions to Brotherhood members - which makes no sense to me - could be an insipid or artificial attempt at placating outrage from the MB - could be the interim operatives are simply flailing about incoherently]
[you really think there's no point in offering some sort of an olive branch to the Brotherhood? Ah... only if they forswear Islamism - but even with that you still get back to 'trust' - why would the military trust the Brotherhood or they the military? Otherwise, what's the point of the coup? The coup only makes sense if one, the military sincerely intends to institute secular, truly democratic governance, which seems unlikely to me, or two, we're heading back to Mubarak era type rule with maybe a more pleasing patina of faux 'democracy' laid overtop of it, which I see as unlikely to succeed because shovelling the 'democracy' cat back into the bag will not be easy and may be impossible - again, the delusionists in the West want to continue trying to convince themselves that Islam and democracy can share power, but that's just crazy and ignores realities our own history teaches us, it's to practice wilful ignorance, which is a pretty good definition of political correctness in general - if Muslim polities wish to embrace true democracy it will mean also embracing secularism in governance - failure to do that will result in what you see and have seen in Egypt: a dysfunctional and corrupt Islamist faux democracy or outright dictatorship or a dysfunctional and corrupt faux democracy managed by the military or outright dictatorship - or chaos - understand, as vile as Islamic extremism is, reality is that in a narrow sense it's rational because democracy, true democracy is indeed a threat to Islam just as it was a threat to Christianity hundreds of years ago - England of course wasn't a democracy under Henry VIII but when he rejected the Pope's messing in his nuptials that was in essence the act of a democrat, he was rejecting absolutism - now not surprisingly he retained claims to absolutism as far as his regency went, but Charles I was to learn a harsh lesson in how fragile a thing that was once the democratic spirit had been set loose]
