Does my right hon. and learned Friend agree that all the evidence is that warring factions seem to be determined to escalate the war, and that, as he has said, our first duty and responsibility is to ensure that the UN force can carry out its assigned task? It was never realistic to expect the UN force to be an invasion force or a force to prevent war. A withdrawal could and probably will be dangerous. It must be properly planned for and managed, which will not be easy. Those who were calling for UN intervention should remember that when we have to withdraw.
