Exactly!! Is is Ukraine, not the Ukraine. I have friends from there and it pisses them off when their country is referred to in that manner. It is like saying, the France, the Mexico, the Spain.
Like THE United States of America?
the country "Ukraine" = "Galicia" + "The Ukraine" (East Bank and West Bank) + "Novorossiya" + "Crimea" + "Bukovina" + "Carpathian Oblast"
There really was an area with fluid boundaries which was a borderland (okraina/ukraina) for centuries (especially 1380 to 1654 and later) between the Lithuanian, Lithuanian/Polish, Polish, Swedish, Ottoman, Austro-Hungarian, and Russian Empires. That would be "The Ukraine" in English as a region, but that is just a part of the present-day country Ukraine.
That is,Ukraine is so much more than just "The Ukraine", which is still a valid historical term.
