Dhawahiri's attacks on Hasan Al-Banna

The recent speech by Ayman Dhawahiri in which he fiercely attacked Hasan Al-Banna and he pointed out his subservience to the monarchy before the revolution was quite interesting.  It may be signaling some new realignments in the world of Islamist Jihadi organizations and trying to discredit the Muslim Brotherhood which is trying to remerge as a "combatant" organization, through various rebel groups in Syria and under different names.
