Obviously, that's why they would be crusades, I'm saying America would trigger it.
Secondly, something close to that figure.
I'm a little disappointed. Did not take you for one the War of the Civilizations kinda guys.
Firstly, most sources put world Muslim population at 1.6 billion. There is a big difference between 1.6 billion and 2 billion as well.
Christians at 2.2 billion.
Hindus at 1-1.2 billion (this surprised me)
The next two largest groups (besidfes the atheists/agnostics at 1.1 billion) are
Shintoism (Chinese) 400 million
Buddhism 400 million
Secondly, in a war at this scale in today's world, numbers are going to count for squat.
A few well placed nukes on Day 1 and it will be all over for the next few centuries.
What does the Muslim world have to fight back with if it comes to that? 100 odd nukes - which don't go further than 2500 kms?
Versus the combined heft of close to or over 3000 still stockpiled in the Christian world.
All of which can reach all pockets of the Muslim world.
Just putting things in perspective. Before this discussion invites the real loonies out here.
