Of the war on terror, Christopher Hitchens once said: I realized that if the battle went on until the last day of my life, I would never get bored in prosecuting it to the utmost. Now comes Bernard-Henri Lévy, who, when asked by Jon Lee Anderson why he supported the intervention in Libya, says: Why? I don’t know! Of course, it was human rights, for a massacre to be prevented, and blah blah blah… Never underestimate the murder men will commit, the mayhem they will make, just to escape their boredom. But every enthusiasm has a shelf life. Even imperialism.
