What's the purpose of NATO? Well actually we have an official answer. It isn't publicized much, but a couple of years ago, the secretary-general of NATO made a formal statement explaining the purpose of NATO in the post-Cold War world is to control global energy systems, pipelines, and sea lanes. That means it's a global system and of course he didn't say it, it's an intervention force under US command, as we've seen in case after case. So that's NATO.
