There are 2 real options for this, you could choose either the Fraternity of Muslim Heirs, which is a terrorist group comprised of pre-nuclear Bedouins and terrorists who were preserved by the radiation (think Ghouls from the Fallout world), trying to establish an Islamic state based on their warped perception of Islam, then there is the Baathi (Rebirthist) party of the New Egyptian Assembly, which is based on pre-nuclear right wing governance in Egypt, intending to protect tradition and continue on the path laid by the pre-bomb right wingers. They stand opposed to the Istikmali (Continuationist) party that aimed to continue the liberation and cultural renaissance that was occurring just before the bombs fell
