I can just hear concerned people the world over breathe a collective sigh relief at the PM’s latest assurance. It may kill a few people and maim a few more, but at least it’ll be legal. Thankyou, Mr Howard. You’ve made our day with that stunning piece of casuistry. Now we won’t need to worry about the prospect of a world holocaust, nor about thousands of civilian casualties and refugees, nor about whether we should even be involved in the war at all. And that’s not all. We now know that the UN have actually said Yes, even if they say No. I don’t understand it in the slightest, so that means it has to be true.
