'But Mr Cameron imagined he could replicate Tony Blair’s achievements in taking on and defeating rogue dictators'
I think that I missed something in the past 20 years - which dictators did Tony take on and defeat? At a stretch you could include Saddam (but I think that the US might take exception to the idea that it was Tony wot dun it), you could certainly include the unelected leader (= dictator?) Brown, but after that I'm struggling to recall any other examples.
