Muslim Brotherhood is founded in 1928 in Egypt. It was one of first normal attempts by an rganized and explicilty Muslim organizationto define a new relationship beetween traditional Islamic values and Western political thought. The group strongly rejected in favor of European style nationalism.
Now, US has designated Muslim Brotherhood as a terrorist group. Like in Nasser era, it would drive some of its members to set a radicalized group which might evolve to violence in Egpyt in coming decade.
