Greenland - Ready to defend itself from Invasion

I know this is a joke but like Canadians, Danes are one of those nations that are pretty peaceful people but you don't want to piss them off.

Apparently Trump is a fan of Seward's Folly, the purchase of Alaska, which gave the USA a reason to raise money using tarrifs. It was a nineteenth century thing.

And don't forget -- Greenland isn't an independent country, it's part of the Kingdom of Denmark.
