In WW2, Henrik Kaufmann, rebel Danish ambassador, aligned Greenland with USA - and Denmark's pro-Nazi government called him traitor.
How much ordinary Denmark people were Nazi, I will leave readers to argue. Stories on both sides.
Europe had many pro-Nazis & anti-Nazis, mixed in most countries.
In UK, pro-Nazi were large minority, especially among aristocrats. They got some power with King Edward 8, then were thrown out in a coup, hidden or masked as KE8 divorcée drama.
In France, pro-Nazi were ??? large minority, perhaps majority at some moment, who came to power with Nazi conquest. De Gaulle "Free France" was minor & unpopular, at first.
In western Ukraine & Baltics, pro-Nazi were probably majorities, as they formed sizable military units to help Germany, & their descendants hate Russia (Hitler's most damaging opponent) to this day.
"Neutral" Sweden & Switzerland made big money, helping Germany. Italy fought alongside Germany.
"Oh but all those countries were conquered or at least threatened" - yes - and why??? Because big elements of their populations, liked it / were pro-Nazi.
World War 2's dirty little secret
As modern war shows us: "Germany" (or whoever) can only conquer the willing. You can't conquer the unwilling.
With Henrik Kaufmann's help: Greenland stood with USA - against half-Nazi cesspool that was Denmark, back then.
USA should have kept Greenland.
Today in 2025, Greenland deserves to be independent nation, under North-American, USA-Canada shield against China & whoever else.
And that should not mean NATO, with its stupid Germans & other arms dealers, who bomb random countries & pursue "forever wars" in Central Asia & Middle East. Fuck NATO. It's evil.
