Do you think Muslims will dominate the world again like they used before?

[Amarok]

I think when you're dealing with large populations it's unpredictable. on top of that the vague definition of what makes a Muslim. For example I know Muslims who would be first on the list of people to be executed by Isis for what they get up to at the weekend.

Take the mongol, Viking or Roman Empire.
I'd be surprised if anyone predicted they were on the rise when they were and I'd be surprised if anyone predicted what would eventually happen to them.
Besides the vague prediction that you can say a super power will rise and old super powers will fall, there isn't much else you could be remotely sure of.

Two things Muslims have on their side in terms of getting dominance over regions of the earth are their breeding rates conversion rates and their dedication.
What they have going against them is divisions amongst themselves and a fairly primitive belief system amongst other things.
