Thanks for sharing David, and while I can emphasize with UK's concerns about whether this is enough capacity based on the current and projected security environment, in my opinion this has significant implications on US strategy also. We have been endeavoring more to pursue "shared" security responsibility with our allies and partners, but the reality is most of our allies and partners have very little capacity to share, and the trend in most cases is downsizing, while potential adversaries such as China and Russia are significantly increasing the size of their militaries, not to mention the continued instability throughout much of the world that we will feel compelled to stick our noses into.
