I think it's already becoming clear that the United States is going to de-emphasize its attachment to Europe. I think there have been a number of statements long-standing from the United States that they're looking for Europe to do more.
If you actually look at the specifics of the pivot, I would argue that it's mostly reducing their force posture elsewhere, primarily in Europe. They're not really adding all that much to the Pacific, at least in terms of ground forces. We're talking about a few thousand troops and redistributing some of the ones who are already there.
Looking to the future, they're making some adjustments to their procurement plans. What is actually changing is withdrawing the brigades from Europe. Essentially everything else is more or less status quo, with the exception of the fact that they're going to reduce the size of their land force fairly significantly.
