@hawkeye10,
I know it's fashionable to be cynical about every politician's motivation, but I don't really think that either Cameron or Sarkozy were motivated by poll ratings. In fact I don't think Libya had any effect on the French Presidential Election at all. It was motivated by domestic concerns.
I don't think much of Cameron, but he's too smart to take advice from you. The one thing he has learned, is not to take military action without UN approval. There isn't going to be any over Syria for the forseeable future at least.
We've got local council and mayoral elections coming up in a few weeks time. Nobody is bothered about Libya one way or the other, although Afghanistan still matters. People are more concerned about tax cuts for the rich, tax hikes on pensioners and pasties, privatisation of the NHS and the £10bn loan to the IMF.
