Kolechia

I think i found the combo

Once long before the Grestin border, there was one large country, the Allied republic of Arstotzka, witch was Kolechia, Republia, and Arstotzka together. but then, Kolechia got into a fight with Arstotzka whether capitalism or communism should be allowed, Arstotzka then built a border around Republia and Arstotzka, (somehow they managed to.) making it no longer the Allied Republic Of Arstotzka, but the Republic Of Arstotzka. then Arstotzka got into a fight with Republia whether socialism or communism should be allowed, then, Republia became it's own country. and The six year war began. after the war, Kolechia and Arstotzka then agreed to make a checkpoint at the Grestin Border, Arstotzkans who were away during the six year war could return home. you know the rest.
