I don’t recall any national president being head of the UN Security Council. Wouldn’t this require Senate confirmation?
That is an interesting thought!
Technically, the United States itself is the President of the Security Council this month. As President of the United States and a superior officer of the U.S. Ambassador to the U.N., he has the authority to represent the United States personally in that capacity. Al Gore was once President of the Security Council when he was Vice President of the United States.
I thought I read somewhere that none of the five permanent members can chair the Security Council.
