It's literally an alliance formed during the Cold War to prevent Russian expansion. Otherwise, Russia would have been invited to join NATO decades ago.

And to say ownership of the most-strategically located nation in the North Atlantic is unimportant to the North Atlantic Treaty is laughable. But you clearly know all of this. You're trying to influence others to believe Russian propaganda.

Russia invaded Ukraine. Russia invaded Georgia. Russia invaded Afghanistan.

You know who they haven't invaded they'd lusted after for decades? Turkey. But Turkey is a NATO member, so Russia can't do shit without.

In fact, there's a wall between Russia and the West of Europe formed by states that have not been invaded by Russia in the last 60 years, and that wall is comprised almost entirely of NATO members.
