My right hon. Friend paints an understandably grim picture. At the risk of over-dramatisation, I would say that this has all the characteristics of a powder keg. President Putin will not adopt diplomacy until he is satisfied by what he has achieved or is forced to come to the table, which renders the point made by Mr Straw all the more significant. Is my right hon. Friend entirely confident that the countries of the European Union will be unanimous in any further extension, and, in particular, that the United States will form part of any such extension, given that this is a matter for the Atlantic alliance as a whole?
