nuclear umbrella would be a choice between Russia (practically impossible)
Let's say the Russia/Ukraine war is over. Russia mends its ties with Europe and says it will be good from now on. The US is ready to annex Greenland. Denmark is powerless and will lose Greenland. Russia calls Denmark and says it can help. If you're Denmark, what would you do?
It would certainly trigger a collapse of NATO. But if the US is serious about taking Greenland, that automatically starts the collapse anyway, right?
Anyway, just all hypotheticals. Interesting to think about. I don't think chances are 0. History has shown us that countries make surprising decisions, including allying with historic enemies, when pushed against the wall.
But people don't actually believe in lesser evil politics, they believe in loyalty (to sides, not to principles). That goes for both politicians and people. Danish politicians will not switch geopolitical alliances, and they'd honestly be color-revolutioned out if they tried, without even the CIA having to lift a finger.
Anti-US propaganda won't fill Danish newspapers, for the aforementioned loyalty reasons. Media people in Denmark (as elsewhere in the West) identify on a personal level with the sensible establishment. Sure, it's awkward that Trump isn't part of that and is currently in charge in the US, but they are convinced things will go back to normal over there, and then it'd be really embarrassing to have failed the loyalty test to the US. "Losing your glove" and all that.
Unless the weapons are under Copenhagen’s control, they’re Potemkin protection. Paris won’t risk its economy being destroyed by sanctions, much less its military destroyed by the American war machine, to protect Danish interests in Greenland.
Why wouldn't the US do the same in Denmark or any other Western country?
What a load of tripe.
