I do NT think so...so many die lately...by foreigners...plus continuously they kill each other...and if that is not enough the Holy Templars will get involved to finish the JOB.
It doesn't seem to be possible if we go by the present trends.Only possibility is that it can happen by default.At present,the Christianity has the largest number of followers in the world but a large number of Christians are becoming Atheists/leaving the faith, ever day and at this rate a time may come when their number reduces to a figure smaller than those of Muslims.Still.the chances are remote for Islam to become a dominant religion of the world,mostly due to inherent restraints in it and world view of Islam in relation to it's perceived links with Terrorism.
AND when y'all have control you'll toss us back into the Dark Ages.
And it'll be ANOTHER 500 years till we can throw off your evil shackles again ... IF you leave any non-believers alive that is.
AND that doesn't seem very likely looking at your track record, aye?
Only because of a rise in Islamic births and a lack of objective education in Islamic countries. I'm not saying that I think that Islam will be the largest religion, just pointing out why it would be.
