Russian lie. Name the treaty NATO broke on "East expansion".
Let me educate you, there is ONLY ONE treaty in regards to NATO expansion. It is called the "Treaty on the Final Settlement with Respect to Germany". "No foreign armed forces, nuclear weapons, or the carriers for nuclear weapons would be stationed or deployed in six states (the area of Berlin and the former East Germany), making them a permanent Nuclear-Weapon-Free Zone".
There is NO OTHER TREATY that bans eastward expansion of NATO.
Statements said in negotiations, which are NOT part of a treaty are just that, negotiations.
Sure-
Try reading something other than what makes you feel good about yourself.
