Carrying on doing what we are doing and expecting it to have a different outcome would seem to be folly. What we are doing now seems in no way to be slowing down the Iranian nuclear programme. If we are to avoid the accusation in two years' time that we allowed the world to drift into a nightmare, how do we and our EU partners take things to the next level in applying pressure on Iran? In particular, those in the Arab world have just as much to lose from a nuclear-armed Iran, so how do we get them to join us?
