Renfrew is right. NATO is just the global form of the military industrial complex that Eisenhower warned us about. WHat need has the US for NATO? What need has NATO for the US? The answers to those questions are all you need to know to decide that NATO should be disbanded. AT a bare minimum, NATO needs to be restructured so that the European nations bear the majority of the expense _of their own defense_. The US, at most, should be a military supplier to those nations. Our troops should just about never shed blood for these leeches.
When the USSR collapsed, American defense contractors went into overdrive lobbying for NATO expansion.
