I would do an excellent job in the White House with my M2TW skills.

First of all I would ask the Pope to launch a Crusade to Tehran, that way I speed up my armies movement points for the march across Europe, and my soldiers get free upkeep (no tax winging from the public). Then once I capture the city I could 'Exterminate Populace' to keep order. Of course if the economy was in trouble I could always 'Sack Settlement' and get maybe 20,000 Florins.

For any battles, I will charge my overpowered cavalry (tanks I suppose) into the Iranian infantry.
