First, let me agree with the hon. Gentleman that NATO is a defensive alliance. That is at the heart of its success. Of course, it now has to think more about the threats from outside Europe, such as terrorism and cyber-attacks, which might require more activism. On his remarks about boots on the ground, in order to squeeze ISIL out of existence, as I have put it, there will have to be boots on the ground, but those boots should be Iraqi boots. It is their country and they should be leading the process. The question for us is what we can do to help those boots on the ground, rather than put our own there.
