St. Paul, Abu Bakr, or Brigham Young?
What kind of successor should the Bab have?
A theologician, a general, or a civil leader?
Should he escape instead of being martyred? Should he found a college to teach technology? Should he convert the Kuwaitis and then they find the Burgan field, an example of the favor of god? They find 70,000,000,000 barrels of oil at a time when most oil wells flowed at 10 barrels a day and a barrel of oil was worth a month's wages, and you will convince many, many, many, people that he is the favored of god.
They wind up taking over the whole of the gulf and expanding as a flood of teachers funded by unlimited oil funds, and strictly non offensive (except they will be attacked and will promptly annex the attackers lands), will be capable of subverting the ruler's control of the ruled.
They pay for the Suez canal after taking over Egypt, and become a central trading depot to rival the wealth of the oil? Hydroelectric facilities at Aswan and more food from more irrigation. Maybe a conversion mission to Madagascar and another up the Nile to eliminate slavery give them access to minerals?
