In recent months, those who previously argued for intervention in Syria have gone quiet. That’s not because the Syrian people are suffering any less—far from it. The death toll is now reckoned to be more than 100,000, 2m people have fled the country and a quarter of the population of 23m is reckoned to be displaced within it.
