I wish I could be more enthusiastic about the events in Egypt and Tunisia – but, as I say in my News of the World column today, the citizens of the Arab world all too often have a choice between a Bad Guy and a Worse Guy. Egypt looks like its choice is between the status quo, the Muslim Brotherhood or a military coup. This is not a 1989-style revolution, there is no Arabic equivalent of Scorpions singing Wind of Change. Successful revolutions normally (sic) have a well-organised alternative government, with a clear route towards democracy. Where is the Egyptian Lech Walesa, or the Tunisian Vaclav Havel? The grim fact remains that Iran is racing towards the bomb, and if they succeed then the Sunni world – in Saudi Arabia and Cairo – will likely follow suit. I’d love to see some wind of change blowing through Arab street, but I still fear that we’re heading for a multi-polar nuclear standoff in the only part of the world which is mad enough to use nuclear weapons. I do hope I’m wrong.
