Not any chance ever.
If Allah existed (I know, a stretch) and appeared in the clouds he could not make the Islamists come to dominate the rebellion.
You see, for Islamists to “Come to dominate” the rebellion - non islamists would have to dominate it before them. Iran set this up, and sinsofsolarempirefan, they have been Islamists since the Shah got kicked out.
I agree with your evaluation. The series of rebellions appear to have been coordinated. The ones who primarily benefit are Iran and Russia. Russia benefits quite a bit because oil comprises a good chunk of their exports.
