My Lords, the noble Lord has enormous experience of these matters. He is quite right. He has had recent experience of some regimes which have had indifferent histories in the context of terrorism. We cannot stop merely having taken action in Afghanistan. It would be a betrayal of all our efforts. This will be a long haul, as the United States administration has said and as the Prime Minister has repeated on so many occasions. In response to the noble Lord's second question, it seems to follow that if we are entitled lawfully to use force, that can never be an option that we can exclude.
