True, I don’t know. It’s not like people think “Oh I have to have foreign policy experience in order to be a senator.”
“actually, I can’t think of any UN ambassador who went on to accomplish anything in politics”

For a position nominated by the President and confirmed by the Senate, it seems singularly unimpressive. There are some impressive intellectuals with great minds, but thats just about it. Other than 19711973 George H. W. Bush, none of them have gone on to a significantly higher role in government.
