You yourself admitted that such a promise, if it existed at all, was given in a private conversation to the first and last president of the USSR, Gorbachev, and therefore such a promise does not have any legal consequences for states.
And such a promise could not even be fulfilled in principle, since according to Article 10 of the North Atlantic Treaty establishing NATO, “The Contracting Parties may, by general consent, invite any other European state capable of developing the principles of this Treaty and making its contribution to the security of the North Atlantic region to join to this Agreement." This means that any European state at any time has the right to express a desire to become a new NATO member, and this issue is decided by all NATO member states, and not just the United States. The US representative had no right to make such a promise, since it was obviously impossible to fulfill.
Listen. I don't care about the Article 10 of the NATO. I don't give a f..ck.
The reality is that NATO has been moving eastward despite the fact that about 20 years ago Putin publicly proposed that Russia join NATO.
When you say that
any European state at any time has the right to express a desire to become a new NATO member I see in my mind a corrupt politician of that European state who has been bought off by Washington.
I believe that sooner or later all these corrupt politicians will be voted out of office by their electorate. This will just take some time.
What I do is I paint a real picture whereas you reply formally and anyone with any brain can see that you give a formal reply which does not mean anything. It's just words without any meaning.
Therfore by your reply you acknowledge that the US ia global bully that can do whatever it wants without any responsibility but as soon as someone like Libiya or Russia speaks the truth the US wants to crush him like a fly. But it won't happen this time. The age of a great empire is coming to an end.
