Often in my featured quizzes questions about Saudi Arabia or Middle Eastern/Egyptian history get taken out because they're not guessed by many people. I have a feeling the AbdulAziz question may suffer the same fate. I find it odd how many people seem totally ignorant about the history here, as to me it seems incredibly significant. But I probably wouldn't know as much about it, either, except for my own peculiar history with the region.
His meeting with ibn Saud would help shape US foreign policy and the direction of history in the Middle East for at least the next 70 years.
For a president whose 3rd and 4th terms in office were completely dominated by WW2 I even think there might be too few questions on the subject here.
