"Withdrawing" to 1990 borders? You mean expelling the states that joined after 1990? I'm not sure that would go over well with the Baltics, Romania, Sweden and Finland. Withdrawal from NATO is voluntary and cannot be compelled.

Yes, the Baltic states in particular were fanatical (um, "single-minded") about getting NATO security guarantees. Wild horses couldn't drag them away.

It will be a withdrawal of US troops and bases with a wink wink. And nothing but impeachment can compel the president to actually respond to an article V call.

USA leaving NATO was floated. I don't know how realistic any of it is, just that these are the terms being negotiated.

At this point, is NATO still alive [1]? I don't think any other NATO country still trusts the US to help when a country has to invoke Article 5.

NATO in its former shape has pretty much been dismantled over the course of last month.

[1] NATO minus the US is still alive, of course.

There are a lot of regional frameworks within NATO. The US doesn't lead all of them. But some of them are probably just paper (not all).

I'd also find it hard to imagine the US not providing enablers like satellite targeting, etc. Or the US being unwilling to sell ammo.

That might have been true last week.

You forgot Poland. :-P

They will never let Poland go because it's a buffer for Germany.

lol, those agreements are just pieces of paper.

Deals don't matter when the counterparty wont adhere to them and there is no third party forcing them to
