Rory Stewart sticks it to both sides:
If you oppose intervention, you call it another Vietnam’. If you support intervention on national security grounds, you call the opponents appeasers and invoke Munich. And you could still do a replace all’ and instead of Libya insert Zimbabwe, Darfur or for that matter Abyssinia, the Hejaz or the Kingdom of Caubul and its dependencies’. Here more than ever what seems to matter is not detailed knowledge of the country concerned but a basic attitude of mind: a high optimism, a reactionary pessimism and very rarely anything in between.
