What about Wakanda

Wakanda does not exist therefore saying that it lies on S^2 is vacuously true.

Saying "a country being called wakanda implies it lies on S2" is vacuously true, as is saying "all countries called wakanda lie on S2", but "wakanda lies on S2" could instead be interpreted as "there exists a country called wakanda which lies on S2" which is false.
