The closest they have is a promise not to deploy nuclear weapons in any new countries.I have that one wrong. I was thinking of the Founding Act. But there is no mention of "no expansion". Sorry.
That implies that new member states are perfectly acceptable.
Although it's almost a silly concern. When missiles from the continental US can hit them in 30 mins, how much difference is it if they were launched from Germany vs Ukraine.
We had missiles in the 80s that were 6 minutes away from Moscow. If we put hypersonics in Ukraine that might drop to 5 mins. Either way, everyone dies.
