The Army have been the de facto rulers and power brokers in Egypt since 1952. Whoever has their support rules Egypt.

Since Morsi was elected President, the Muslim Brotherhood have been attempting to force through their own party's agenda and whilst concentrating on that the country has basically been left to go to hell in high gear - that is what the current "opposition movement" and the Egyptian people are complaining about.

Events reached the point where the Army drew a line and issued their ultimatum. When that ultimatum was ignored they acted in the only way they saw fit in order to prevent a downward spiral into chaos and civil war, they have imposed an interim Government focused on two facets of governance - the introduction of stability with the promise of elections early next year, by which time political parties hoping to take part will have devised their proposals for governing Egypt whilst avoiding the mistakes made by Morsi & Co.
