 But the issue really is, I mean, because we don't have that full element of data, and this is what the review is trying to do, that it's easy to say sort of 2% because that's a NATO baseline, and 2.5%, say 3%. Well, I think when you speak to people within NATO who run the NATO defence planning process, their overall assumption is that even 2.5%, if the whole of the alliance was to move to 2.5%, probably wouldn't be enough, bearing in mind the threat.
