As world opinion becomes more outraged (and US diplomacy looks more impotent and clueless) on Syria, a poll in France casts light on the growing clamor for yet another Middle Eastern war.According to a poll published by the prestigious French newspaper Le Monde, 58 percent of those polled favored a UN backed intervention in Syria. (Alert: the link takes you to an article in French.) Even more striking, once supporters of the far right Front National are taken out of consideration, almost three quarters of the French right and two thirds of the left support such an intervention. (New French president Francois Hollande has said that such an intervention “cannot be excluded.”)This kind of poll will inevitably drive more talk of war, but it is interesting to note the limits of that support. Only 50 percent of the French favor French participation in a UN-backed military effort. Given Russian and Chinese determination to block another western intervention in the Middle East, it is likely that any such intervention would have to take place under NATO. That would be harder for the French to support, especially on the left where many still see NATO as an instrument of American power that France needs to oppose.Unless things change, that means that the French are likely to march in the streets and write letters to the editor about Butcher Assad’s Syrian horrors, and reflect at length on the vast moral distance between their own keen enlightenment and strong political values and the sorry state of the Arab world, but otherwise do very little.Given that Germany is strongly opposed to military intervention in Syria and that Britain shows no desire to lead the charge, Europe is unlikely to provide clear policy leadership on Syria. The Obama administration can’t lead from behind this time; at present it appears unable to lead at all.
