Good luck on filibustering Iceland, too, since it is actually in Europe
Iceland does seem a bit of a stretch, though time will tell...
and along with Greenland was a major reason why Denmark kept the same levels of respect and prestige in Europe, after it got stripped of Norway. If Denmark was seen to be losing them then they would have to fight back furiously, and I have no doubts that they would call in alliances to win the war, and probably petition the UK to help too.
Yeah, but it's more a matter whether the US wants to invest in taking it during a time of chaos. The Danes may try to fight back...but they're too close to the Liberal War Northern Theatre to be able to project power far from home without risking a lot more than Greenland. Her allies are out of position to help that far to the Northwest. And British interests are not optimal for the Danes to count on their intervention.
Denmark's navy shouldn't be underrated, too - it was bigger than you might expect, and well-trained, and probably could slap the US Navy around if it avoided the one-on-one fights that the USN kept pulling in the War of 1812 - it certainly was capable of blockading any filibusterers to starvation.
You might be surprised....
It's one thing calling a filibuster of Alaska as questionable yet believable, but to try to argue the same case for Iceland particularly is just a little bit too far - especially as a filibuster, which was hardly something European states approved of. I think if the US tried to actually filibuster European soil, they would have hell to pay.
A real filibuster attempt at Iceland would probably fail, yes. Then again, so did the attempted filibusters of OTL.
I guess at the end of the day, the US if it were feeling a little too arrogant could try it...but they would surely lose, and they might invoke the wrath of one of the Great Powers while they were at it...
The only Great Power that the US really has to fear is Great Britain - other powers would have to go through the UK to get to the Americans. Without at least tacit permission from the UK, any Great Power would be looking at a war far from their supply lines and against both the US and the Royal Navy.
