They're making more global strategic choices. So if you recall reading the U.S. strategic guidance of January 2012, which was the so-called pivot guidance, it clearly articulated a diminished appetite for what American contributions would be, or how they would morph. So for example, in areas of Africa where they recognize terrorism as still extant or terrorist groups, they wouldn't deploy large forces but they would still meet the problem with either special forces, direct actions, drones, or whatever the case might be.
With respect to Europe they were also very clear that they were not abandoning NATO, but they were going to reduce their contributions to NATO in the expectation that the European allies—many of them also G-7, G-8 nations—would contribute more of their fair share as opposed to the United States funding NATO from 50% to 60%. So it has had an impact, but they have a much more global view than we do.
Ferry, I don't know if you want to add to that.
