Russia moving their nukes to Georgia is the most telling sign yet that they’re not serious. Our intercontinental ballistic missiles are marginally closer to you is not the brag they think it is. It means they’ve given up on military superiority and are now resulting to chest thumping in an attempt to intimidate, they wouldn’t do that if they still had a functional military.

So I’m reasonably confident that Poland is safe from Russian aggression.

I also can’t really see the US going to war in Greenland. It’s a wholly unpopular idea both with civilians but also with the US military who know that all it would result in is them losing a significant chunk of their forces to hypothermia since the US is very weak in cold weather combat. They already have a US air base in Greenland, controlling the rest of the country wouldn’t increase US national security and the only person who thinks it would is Trump.
