Basically after years and years of communist leaders and religious high-ups enjoying drug/sex trafficking and population manipulation, the Muslim Brotherhood decided to be the one who was the best instead of co-existing with its satanic siblings. They wanted to have the whole world under their thumb, so they went after the American political regime first, as well as the Rothschilds European Jewery. But obviously they wouldn't last in an outright war, so they set up small plants and infiltrators.
