Rep. Earl L. “Buddy” Carter (R-GA) released the following statement today after introducing a bill authorizing President Trump to acquire Greenland and renaming it Red, White, and Blueland:
“America is back and will soon be bigger than ever with the addition of Red, White, and Blueland. President Trump has correctly identified the purchase of what is now Greenland as a national security priority, and we will proudly welcome its people to join the freest nation to ever exist when our Negotiator-in-Chief inks this monumental deal.”
They care about money. If they don’t go alone with it they probably get fined. So yeah, I think they will.
And it’s not uncommon. Lots of countries don’t call other countries by their names. Japan is Nihon. China is Zhōngguó. Germany is Deutschland.
But those are for historical reasons, changing it specifically to be different is nuts.
