It is worth saying that the street can rule but it cannot govern. Egypt is deciding its own future just as Eastern Europe and Russia decided its future. A working alliance with the Muslim Brotherhood in the current crisis is not surprising. It is an organization that will be there. We have seen in Lebanon and Gaza that the ramifications of enabling political Islamist organizations impact on the future. Other organization need to establish leadership bodies within the movement and "make the rules" that even the MB is bound to follow. But beware of sleeping with the tiger, cause when he wakes he might be looking for breakfast.
Likewise, army rule in Turkey did not prevent the oppression of the Kurdish nation and its people. It has not provided democracy or equal rights. And the continued influence of the military in governing Egypt will not be changed. In this sense, this is not a revolution at all. More like a coup from the bottom or a change of faces at the top.
Structure is something that needs to be formulated to give the democratic process a real world context. To date everything is focused on the personal reign of Mubarek. I am in solidarity with the hopes and aspirations of the Egyptian people, but if they are to govern then the place to start is with the Constitution of their nation.
