Your main points, that the military has a bloody and corrupt history in Egypt, is well taken. And it is ironic that the opposition of several years ago was against army rule but now favors army intervention to depose Morsi and to facilitate a democratic transition. Nevertheless, Egypt was plummeting into a failed state ( with investors pulling out, debt growing, tourists being attacked) under Morsi; hopefully a more inclusive and competent government may emerge if the transition is successful. Morsi and the Islamists showed themselves incapable of governing and as you note, the economy was sinking quickly. In addition, a decree by Morsi eliminated judicial oversight of his actions which in essence subverted the entire democratic system.
At least the coup has broad Egyptian support, as does the army currently. How long that will continue is anybody's guess however.

Also, there was no provision in the Constitution for impeachment due to coercion of MB. I think MB brought this on themselves. They were given a chance but they blew it. He also did not heed to early elections.

The army in America takes an oath to protect the Constitution not the elected officials. I think that is the same in Egypt. I am not sure. The Egyptian military supported the will of the people during the people's recent revolution. During the "Iranian summer" when the students and people protested, the Iranian military came in and squashed the will of the people and ended the movement.

Welcome back DK.

No president has the right to undermine a country's Constitution. To defend an Islamist president who was preparing the grounds for a Khomeini-like transition to a Theocratic State, demonstrate the inability to make a concrete analysis of a concrete situation.

Can't they ? ...

Well the French President did so not long ago t by changing a fundamental and deemed irreversible Code Napoleon inscribed in the French Constitution by allowing Gay Marriage despite massive rallies across the country disapproving that decision.

All that thanks to an unrepresentative Parliament precipitatingly voted in immediately after the Presidential elections thanks to dubious pre calculated and ideologically incompatible alliances allowing the socialists to elect 20 Green Party Parliamentarians whose very own candidate barely represented 1% of Public opinion in the last Presidential Elections where as the French Far Right National Front candidate which rallied 18 % of the votes nationwide could only get 2 deputies elected in Parliament. 

I did not see the French Army topple President François Hollande for that matter ...

A Coup is a Coup ... no matter which way you wish to look at that not so "concrete" democracy ...

As for the "Khomeiny Like" Transition maybe you women should have thought about that first before massively putting on a chador and shouting "Marg Bar Shah" instead of demanding reforms of the System of government which gave you ladies so many rights including to that Nobel Peace Prize icon of yours Shirin Ebadi who became the country's first female Judge under the Shah's judiciary system yet to this day refuses to apologize for her own poor choice back in 1979 which sacificed two generations of Iranians regardless of gender and sexual orientation ... 

Good Day Madame ...

Mr. DK, drink some cold water! You cannot generalize the entire Iranian women into one group who according to you wore chador and... Well, you could, which would show your level of thinking.

With coup or without, Egypt went through one big change last week. What does it have to do with you? Same about France. What is your beef? Really? LOL!

Those who didn't wear Chador to submit themselves to the revolutionary crowd still did a grave disservice to Iran by their passivity. 1978-9 provided enough time for them as well to organize against the coming flood but they chose to hand Iran to Mullahs with their silence. Except for a few demonstration of a few thousand, which were ridiculed by the entire naiive nation, the orphan Iran was left to be molested then slaughtered. We assassinated Shahpour Bakhtiar right in Iran and in 1979 not in Paris of 1991, and not only him but Mashrooteh and its constitution. One can blame MRP for he had not left any friends for himself. What an Irooni statement; collectively lift responsibility off of our shoulder and shift the blame to someone else. One's country is not a schoolyard where I do this because you did that. We all did it together either passively or actively. And now we have become so ashamed of our existence that our wish has reduced to a plea to the world to bomb Iran and erase us from the surface of earth. 

It's a coup, no doubt.  But better a military coup than a civil war.

PS. good to see you back, DK.

I really don't care for that country.

But I am glad Morsi gone as he looked suspiciously hezbollahy.
