So Cameron has got his 'Churchillian' moment! Hurrah!

Apart from that, he hasn't got any sort of coherent plan but, gosh, he's now got lots of opportunities to talk tough and look determined and heroic! Perhaps pictures of him in a headscarf will appear in the Sun under the headline, "Gotcha!!"

And, of course, when the whole sorry mess disintegrates into complete chaos he'll get away with it (although lots of innocent non-combatants in Syria and the UK won't). I suppose there's a faint chance that, about 40 years down the line, some latter-day Chilcott will reveal what an utterly clueless, opportunistic, cynical prat he is but he probably won't care by then.
