This is the top post this morning? The issue won't come to military action. But if it did, Denmark could exercise all they want, and it would still last about ten minutes. Not sure how this is relevant to anything.
You are not sure how it's relevant the main pillar of NATO is openly talking about military action against one of the founding members of NATO?
It's relevant since everything in your life right now if you live in any Western country is reliant on this partnership since the end of WW2. If it changes you'll live in a different world, not sure how this is not relevant to you.
I don't think there's much doubt about a US success if it came to that. The relevance—and yes, this is highly relevant—is to determine what would be left of the current world order after those "ten minutes".
How can you be so certain with that diaper-filler in chief?
Deploying troops looks like an attempt to dissuade invasion by highlighting that the optics of US troops capturing (hopefully not shooting at) NATO troops would be real bad...
Imagine Afghanistan but against a modern, professional army and with the weather trying to kill you.
Which isn’t to say that it would be impossible, but certainly it would cost more in terms of casualties and money than most Americans realise.
The US understands cold.
The US may have some understanding of the cold, but the nordic countries have far more, and are far better prepared.
