So? Ever heard of colonialism? Greenland and French Guiana are European too. So are the Dutch islands in the Caribbean. Many parts of the world were European once. French Guiana is a part of the European Union where it’s inhabitants get EU passports and pay with the euro. The Netherlands and France share a border, on the island of Saint Martin. Canada was European too when it was a part of the Commonwealth. Let them join again but this time independent.
Easy there, Heinrich Himmler
