If there are 5 people saying “the Ukraine”, I am one of them. If there is 1 person saying “the Ukraine”, that person is me. If there is no one saying " the Ukraine", I am no longer alive. If the entire world says “the Ukraine”, I will support the entire world. 'Till my last breath, I will say “the Ukraine”.
I’ve called it Ukraine for decades (I’m not even an east coast yank!), because I wasn’t born in 1975 and place names change sometimes.
Czechoslovakia is another one that dates people’s geography knowledge imo.
