Ans.A bit more than some ; Just think, If it wasn't for the Jews Islam would never needed to exist and I find it interesting that the two major religions of our time were borne of The Middle East and look where that got us all MUQ !
It is like saying, if it was not for Adam, there would be "No Humans on earth"!!
The religion of God, the religion of Islam is what was the religion of All prophets of God, irrespective of the regions.
It is not correct to say that Islam came only because of Jews.
As for your second Remarks, just spread the circle a little wider, All Major religions of the world, came from Asia!!
Hinduism, Buddhism, Judaism, Christianity and islam , they all arose from Asia!!
