I can't say I have a definitive answer, but my thoughts echo (at least SOMEWHAT, not 100%) what this writer has put (fairly succinctly) in the following two paragraphs (caveat: these paragraphs only... I'm not aware of what all this writer says or supports beyond these):
[quoting Don Koenig]
"I think believing that the Antichrist is Muslim can be a big danger and a trap because I believe the real Antichrist comes into power through the wars against Islamic fundamentalism. So those who fall into the trap of making an Islamic Beast might actually help create the platform for the Western Beast Antichrist to stand on and rise to power and take over the world as the world’s savior that saved us from Islam.
"I also want to point out something else. Believing that Islam is the Beast system is not at all logical. It is obvious that Islam with all its laws will never be accepted by the decadent West. It is also obvious that any system that unappealing to the West could never take over the world by force. So the logic of a Beast Antichrist out of Islam escapes me. Also, if the Beast were Muslim and his God was Allah, why would he demand to be worshiped as God? Those in Islam will never accept the worship of a man claiming to be God. The whole concept of an Islam Antichrist is fantasy."

So, this general idea ^ , IMO.
I'm picturing more like a squeaky clean[-appearing], John Wayne type...
