It is strange in Islam, that the Shite Muslims believe Mohammad's son is going to return to Earth and rule the Earth for 7 years. They believe he will make all nations worship Allah. Sound familiar in Revelation.
If all the Muslim nations across North Africa, Middle East, Central Asia, including Pakistan (which has nukes), and Indonesia, would unite, they would be a super power. They would have about 1 billion people, tons of oil, nukes, etc. They would be something to contend with. Thank goodness so far they can't get along with each other much less the rest of the world.
They could very well be the one world religion. All they need is a powerful charismatic leader to unite them and Israel is right in the middle of the mess as in scripture and prophecy. Could be the 10 nation confederacy in Western Europe and the Kings of the east with 300 million troops will wage war on this superpower and end up in Israel.
The Bible was written from an Israel and Middle East perspective. The whole world back then was the Middle East and Roman Empire area. Again, just my opinion.
