As Senator Quinn said, America is in a difficult position as it adjusts to being the sole superpower. We do not want to go back to the balance of terror that maintained peace of a sort during the Cold War, or Lord Castlereagh's balance of power within Europe, which was a recipe for later struggles. America will have to learn to live with being a superpower, part of which is ensuring support for international organisations. We must cling to the hope this can be settled by means other than war. That does not mean giving Saddam Hussein, who is quite clearly in breach of the resolution, unending rope but it does mean making every effort in the days and weeks available to ensure a peaceful resolution is achieved through the United Nations. There is a challenge for America here, too – sending troops and putting them in position to show that it really means business – calling Saddam's bluff – must be balanced with the difficulty, as the Duke of York found, of marching them down the hill again. That is something we will all want to bear in mind.
