I'm a born-again Christian, so here's the biblical perspective, according to my current understanding (Joel Richardson a good resource to check out).
Iran is going to get crushed but by Turkey in a Sunni/Shia conflict, that revolves around who is going to lead the revived (final) Caliphate. The Caliphate (Ottoman Empire - Turks) was last defeated in WWI. Keep your eyes on Turkey as Erdogan steadily turns the country into a dictatorship and they roll into Libya, eventually invade Egypt, possibly Saudi Arabia, Greece/Cyprus?, the Balkans?, they will conquer Iran (Daniel 8), etc. It's the Ottoman Empire that is going to be revived, not the Roman Empire. The pope is leading the push towards the one world religion though.
The final goal is of course Israel. The Muslims did not prevail in 1948, 1967, 1973, etc. This time they're going to come with millions of fighters from North Africa, the Middle East, Central Asia (the Stan countries), even the Far East (Malaysia says they're ready for the call of Jihad) and Israel's nukes will be useless because they're not gonna nuke their own country. Once the next Dem gets in office, Israel will be on its own.
Have you ever wondered how the tiny country of Germany caused so much death and destruction during WWII? Because they had supernatural evil on their side. Imagine millions and millions of Muslims hellbent on Jihad, with the powers of darkness behind them. The world is only going to get worse and worse before Jesus's return.
That said, I can't wait to hunt tomorrow morning!
