I think there was big concern about NATO enlargement. It was, of course, how much more difficult it would be to achieve consensus. Simply, the more people you add, the more difficult consensus is to achieve.
People on the inside tell me that has not been the case. They still find it is possible to achieve unity and come out with common positions that are meaningful. It's no worse than it ever was. I do think we ought to recognize that NATO is fundamentally a political and military alliance. Of course, you need both. There's no point in having an impotent discussion without sort of the force to back it up.
I passionately believe that the political side of NATO is vitally important and is something that we should take more advantage of.
