Here we go again. Tony Blair sounds off about the threat from Islamic extremism, and how we may have to make unpalatable deals with dictators in order to resist it…Reaction varies, from experts who think he’s simple minded, to cynics who point to his track record on intervention and his total failure to mention Israel and the Occupied Territories, a big stumbling block he’s supposed to be removing. You have to wonder why anyone ever thought they should pay him any attention, and the answer – sadly, ironically – is that he won three elections on the trot. That surely can’t – can it? – be the model of what’s required?
