I am not saying you're stupid or misinformed, I'm saying you're missing the point. Understanding what Trump wants doesn't require you to understand geopolitics, it requires you know clinical psychiatry.
What do you expect (e.g.) Norway to do except disentangle, when their PM sends this text and gets back this response? And note that Finland's president (Alex there) has been one of the big proponents of continuing to engage with Trump. So, honest question, what should Finland, Norway, etc, do?
Trump absolutely drives this. You're deluded if you think this whole thing comes from the DOD. He is in effect a king at this point and he rules by posting in social media.
These are military decisions. These are 50-year plans.
