Sometimes, pictures are worth a thousand words....

What a shock - the US chief diplomat meeting with the leader of an important foreign county which is not at war with the US, and which most Secretaries of States after WWII have done (including her two immediate predecessors)!

Very true. I need to make billions to support my younger Yugoslavian wife, who really isn't that good looking though for me she is, because she only loves me because of money.

This might be nitpicking, but Yugoslavia fell apart 24 years ago. And I doubt you even have the excuse of having grown up when it existed.

This might also be nitpicking, but Serbia and Montenegro retained the name "Federal Republic of Yugoslavia" until 2003. Also, calling yourself "Yugoslavian" simply means you're from the Southern Slavic areas, and isn't necessarily linked to any specific nationality.

Yes and since Trump's wife is from Slovenia, this is not relevant. And Yugoslavian had never had this meaning in English (or any Southern Slavic language for that matter) - it has only ever meant a inhabitant of Yugoslavia, since the whole term was borrowed only as a name of a country. For an obvious example, Bulgarians are never called Yugoslavian, though they would be according to your theory.
