The Wikipedia article for the World Bank Group states that:
"Traditionally, the Bank President has always been a U.S citizen nominated by the President of the United States, the largest shareholder in the bank."
So this does not feel like a protocol for what is by its definition an internationalist organization, so my question is actually several really:
Why must they be an American citizen?
and of all things, nominated by the President of the U.S? Why are people from other places in the world ineligible to for nomination for President of an International organization?
Has the U.S been the largest shareholder for the entire history of the organization?
