> So what? You're claiming the alliance is irreparably broken, who cares about the text of a treaty

The alliance is broken, yes, and everyone is treating it as much. Kicking the US out, other than being impossible, will only piss off the petulant children.

> Did he invade Greenland? Bomb Canada? Those are the specific outrageous things he said that we're talking about here. As far as I can tell, he created his outrage and distractions there, and moved on

He was damn close to attacking Greenland, so much so that various European nations felt the need to send soldiers there to show they're commited to defending it. It doesn't matter that he didn't actually do the absurd.

> I don't think you get it, either: how long can you maintain that attitude without the irritant (the 80-year-old person that is Donald Trump)?

Geopolitical priorities and alignments take years to shift. So does military procurement. Once the US is no longer reliable, it will take years of reliability before there is a chance to mend the relationship.

> Also, you're acting all outraged, but present in your messages (but unacknowledged) are other and more tangible violations of trust, like European countries shirking their military spending commitments and letting their militaries decline to disrepair, because they expected the US to defend them forever for free.

I'm sorry, but that is just pure grade A American bullshit. It's insulting to everyone's intelligence to spout such nonsense. Various European countries spend to various extents. Nobody, is getting protection for "free". They're all pitching in to different levels (some like Poland, France, UK, definitely more than others). And the US was getting plenty in exchange, most notably bases to run their famous and intimidating logistics. The US definitely loses more out of losing those than European nations that have the British and French nuclear umbrellas if it push came to shove.
