So since 1952, the main Headquarters of the United Nations has been in New York City - even though the earliest meetings of the General Assembly took place in London and planning for what would become the UN also took place in San Francisco.
Now with that said, is there any other city besides New York that could have been chosen as the main location for the U.N. headquarters? I'm sure American influence would nix any non-American city being chosen, but it seems likely that Washington or one of its suburbs would also be a non-starter for other nations.
Personally, San Francisco seems to be a good choice, but admittedly, I'm not sure if it would be discounted for being too far from Europe. Thoughts?
