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

If you can ever find it where you are there is a great little book called "The Early History of Christianity" by J. P. Jenkins.  It does not focus on the West but rather on the early spread of what western xtians would call heresies ( Nestorian, etc) which spread all the way to China while Europe was falling apart during the Dark Ages.  With rare exceptions the xtian and muslim groups got along quite well.  Until, the Mongols that is in the 13th century.

I'll take this book into my consideration. Thank you for mentioning this info.
