I thank the right hon. Gentleman for those comments and his support, which is all the more welcome from someone with his experience in such matters. I can assure him that we have carefully looked to see that the deployment can be sustained. We believe that it can be sustained.
I agree that if the air strikes are successful, we need to get the political process back on track. That is our aim, politically. I also agree with the right hon. Gentleman that we have no alternative if NATO is to remain credible. That is not our principal reason for acting, however. We are not acting in pursuit of a theory of credibility, but we have given certain undertakings, and if we do not abide by them, we will not have credibility in the future.
