Sure. But NATO is/was quite different that what is being proposed, at least as I understand it. Not only did it have the US as a strong foundation to build upon, it also had a clear remit early on to defend Western Europe from the Warsaw Pact. As that remit has expanded and morphed over time, NATO has become the less and less stalwart. The new EU body has none of those early NATO strengths and all the later NATO weakness, in spades. Hey, its up to the EU to try out what it wants. I just think it is a tough thing to cobble together on spec.
