From what I've read; this probably will NOT happen.
The Shiites and the Sunnis have been around since Mohamad died, and neither has managed to get the upper hand over the other.
Genesis 16:12"He will be a wild donkey of a man; his hand will be against everyone and everyone's hand against him, and he will live in hostility toward all his brothers."
Yes, I know about the world’s oldest and longest-running “Hatfield - McCoy” feud.
In past years, every time Islam threatened the West, the West rose up to smite them down.
We’re at or near that tipping point right now. Something has got to give way - either Western Civilization submits to Islam or Islam gets put back into the 7th Century again.
Islam and Western Civilization CANNOT “co-exist.” Gotta be one or the other.
I prefer Western Civilization, and am appalled that so few “world leaders” are willing to fight to preserve it.
