If changing the head of the system is all the protesters in #Egypt hope to accomplish, then this is something the system knows how to do anyway, and has no reason not to do it. I do not think there will be any confusion on the part of power on that issue.
If the protesters want more substantive change, they can potentially utilise the current momentum to advance that, and in the process, create indecision on the part of power as to how to proceed.
I have always said that a single-minded focus on #Sisi is a mistake, it was before, and it is now.
