The current dictatorship in Egypt deals with the Muslim Brotherhood in the same way pro-US capitalist dictatorships dealt with communist groups. The Muslim Brotherhood is still very popular in Egypt, and in the last legitimate election won close to 50% of the vote. I don't support them but their views are generally closer to Christian Democracy/socialism than you'd think.

Fact is that Egyptians are opposed to this, just like most other people in Arab or Muslim majority countries are. Their government is authoritarian and just does what suits it best, which in this case is to appease the US.
