Just for the record, you descended into moonbat territory when you attempted to discount the re-establishment of Israel.
Except for this really huge hard to explain away evidence, please give me some things easier to deny.
I suggest the temple will be rebuilt after the fall of Islam.
Allah, as described in the Koran and the Hadith has invested himself in Mecca and Medina. If he exists, those two cities holy to Islam cannot be destroyed. Leveling them will topple the religion, unlike the God of the Bible who is not invested in places, but in people.
Not to be contentious (really), but there is no known principle which proves that Allah cannot exist without Mecca and Medina. Such speculation may be true...or it may not. But there is no way of knowing.
One additional point.
If Allah is not just some mythical moon god but one manifestation of a multifaceted spiritual being (like a fallen angel--Shemyaza/Semyaza/Semjaaza for example), we have no idea how the being using the name/pseudonym of Allah might behave or what laws he is subject to (except, of course, for what we read in Holy Scripture--and there is much anecdotal evidence to support that).
BTW, based on what we see of the behavior and personality of this Islamic Allah, there is (from a Judeo/Christian POV at least) little doubt that he is indeed not just one of the fallen angels, but one of their leaders.
We can surely hope.
