Probably many greedy reasons, but my personal favourite speculation: annexing Greenland surrounds Canada and stops any potential aid by its NATO allies in case of an invasion, since annexing Canada is one of the stated objectives of the US now.

In terms of strategy for actual national security, they already got all the access they wanted, if they wanted more all they had to do was ask. If they’re the ones doing the attacking of a common ally, though, they wouldn’t get that access. So it’s only of added strategic value to annex instead of maintaining the alliance if the goal is to attack members of the alliance.

Korean democracy is not dead yet!

Me, checking what the damage is: oh good, my European defence stocks went up 2 to 4 percent today while the American stocks are tanking, happy days!

Me, after thinking on it a bit longer: oh God, my European defence stocks went up while the world economy is taking a hit, better get ready for whatever’s coming

While you are staying, your productivity is fueling the economy, and the taxes you pay go to the government you dislike. If you flee, that’s a big economic difference you’re making over the years. I guess if you fight symbolically but non-pragmatically and get arrested, they have to feed you and house you in a prison which will cost a little extra, but compared to your non-productivity that’s just a small bonus. Fleeing also means you get to proactively contribute to competitors and reward them for being a better place to live, which in a way doubles your economic impact. There’s a reason the Berlin wall was built and North Korea executes 3 generations of the families of defectors. People are valuable, and they can’t afford to lose too many of them.

On the other hand, if your threshold for fleeing is too low, there are no competitors to support, because every country has their issues, and some may be at a risk of the same developments as the country you’re fleeing from, making it a pointless exercise. And your loved ones could be essentially hostages that can be used to make you stay.

So it kind of depends, but at least the cowardice argument seems pointless to me. Pragmatic small-scale effectiveness tends to beat symbolic perfectionism at making an impact.
