To bring about the Mahdi Iran must be destroyed to destabilize the entire region. Once Iran is destroyed by the inevitable war with the US. The Israelis will rule the world for a day which is like a week. The US will most likely collapse and pull back from the world stage. Pax Judea will seize upon all the former US bases in the Middle East and will rule the world with an iron fist until the Dajjal arrives and the sea of Galilee dries. Then the army waving the Black Flag of Khorsan shall march to Jerusalem and it will be a level battlefield once and for all.

If you look at it from an Aryan Perspective the Army from the Himalayas led by Kalki (black flags of Khorasan) WILL rid the world of evil and usher in a new golden age by destroying the Jewish Kabal.

I personally think the Nordic Aliens see the rule of the world under the Jewish kabal as a terrible thing and world war brown as the last true step before the Aryan Yeoman can finally reclaim their place in the caste system of the races.
