The tale in which we are the unwitting characters has only two possible conclusions. Each is the product of those who frame the conflict - not the ones who have that conflict forced upon them.
The two endings are:
The whole world is Mohammedan.
~OR~
There are *no* Mohammedans in the world.
Again - THEY have set the terms of conflict.
That pretty much covers it.
That has been true sine Mohammed was raiding camel caravans.
