I think I would agree that it's not just rebalancing. I do think there is a shift in priorities and emphasis, particularly in how assets are going to be deployed. I would agree that this will create issues with respect to the relationship between the United States and France, the U.K., and Germany, in particular, about the U.S.'s commitment to Europe, but I think we have to have a little bit of a historical perspective here. The level of commitment of the U.S. to Europe has always been a concern of the Europeans. It's an ongoing challenge.
We think back to the Vietnam war, we think about periods where the United States was engaged elsewhere. That doesn't mean that NATO is irrelevant, but, yes, it means it is harder than it was, for example, during the wars in the former Yugoslavia, to make the case that NATO is the pinnacle of U.S. defence and security concerns.
It definitely needs to be managed politically, but we mustn't forget the degree to which the U.S. still sees NATO as a hugely valuable tool of its own foreign policy and a mechanism for exerting its influence in meeting its objectives.
