At first glance it may seem that el-Sissi is trying to maintain order by pulling other Arab nations into the fight against ISIS.
I just went to his wiki page and two things jumped out at me, and surprised me.
1. His religion is listed as Sunni
2. His forehead displays a prominent bruise. The bruise is there to show other Islamists how devout he is, that he faithfully bangs his head on the floor 5 times a day.
Those two things didn’t help Anwar Sadat, now did they?
