You have not had a better opportunity than now to undermine the coup and get rid of Sisi, not since the Sharm el-Sheikh Economic Summit.
Sisi’s legitimacy as a ruler has never been derived from popular mandate, it has always been derived from his compliance with the agenda of the global owners of capital, and his ability to impose by force the neoliberal policies they dictate.
If you prove that he cannot fulfill his institutional role within the imperial system; if you can prove that multinationals and foreign investors cannot profitably do business in Egypt as long as he is in office, he will be removed.
Yes, the global power structure will attempt to replace him with someone else who can serve them more effectively; but if you are able to force them into this position, it will be impossible for them to ever ignore your will again.
