In the defence realm, I did not encounter any problems in terms of building a collaborative approach. Clearly on some issues, sovereign nations are going to make their own policy and they won't always agree. That's certainly the case with ballistic missile defence. That's fine. The important thing is to sustain the dialogue and, where each sovereign nation shares an interest in defence collaboration, to advance those opportunities. I think there are many more opportunities to build on the foundation that exists today, which need to be advanced.
