The right hon. Gentleman has enormous experience, and I think he speaks with enormous wisdom. The first point I would make about what he says is that it is because of those deadlines that have come and gone, and the pledges that have been broken during the tragic three years of this conflict, that we are being very careful in the wording that we put forward now, to try to get a wording that could stick and that could have the support of all sides.
The right hon. Gentleman is absolutely right that there will be very serious consequences if we do not see progress. He will understand if I do not spell out to the House what those consequences are. All I can say is that I do not believe that our allies are in any doubt of the extremely high priority that both we and the Americans attach to this, and I think that is very significant.
