Literally EVERY SINGLE ONE OF THEM is not american. 3/4ths are straight up non-american, and of the quarter that is "american", they're all people who were born outside america, and then moved to the USA after their stay at a university there. Like, seriously. Just go to the fields medalist page, and sort by most recent. LITERALLY NONE OF THEM ARE AMERICAN.
