This is why it was so problematic to end the democratic experiment so early in Egypt, fearing that Egypt would turn into Iran. I doubt that an Egypt, that very much relies on beach tourism and western investments,would be able to do what Iran is capable of doing through its oil.
During the protests, Morsi was arguing that foreign countries were behind the unrest. As conspiracy theories are rampant in the muslim world, such talk gets drowned out. When Erdogan uses autocratic measures, especially since the fall of the Muslim Brotherhood, he uses the argument that his opponents are aiming for a coup like they did in the 90s. If the muslim brotherhood comes back to power, it can probably use such an argument to crack down on dissent.And it will be much easier to do so than if there hadn't been a coup.
Though surveys in Egypt can be unreliable, this is the numbers that Gallup reported of the support the Muslim Brotherhoods party, Freedom and justice party, had.http://www.gallup.com/poll/163796/egyptian-views-government-crashed-overthrow.aspx
