The idea of conflict with Greenland is kayfabe - it's all posturing and bombast. There's a significant probability that the Trump admin attempts and possibly succeeds at buying Greenland. Not usual for the last 5-6 decades, but in a historic context, fairly normal for nations to do this type of thing. There are legitimate strategic and economic arguments for it - not sure that I buy the arguments, but I can certainly entertain the ideas.

Iran is a sticky situation. It looks like the Trump admin is poised to chip in some missiles if it looks like they can tip the balance definitively for the protesters, but according to the intel accounts, the current positioning of assets means they're still at least a few days away from acting. That could be a deception and at any moment the current regime could get erased, so it's probably prudent to get the hell out of Dodge before the missiles start flying, or before the total crackdown and enforcement gets escalated, in the other direction.
