It's good to have the thesis confirmed yet once more: amongst opponents of the wars in Afghanistan and Iraq, there are people who think that they had reasons for opposing those wars whereas (they also think) the supporters of the same wars had no reasons - because there were none. Enter Sir Simon:
The sole reason for going to war against Iran is to go to war against Iran. That is how we went to war against Afghanistan and Iraq.
OK, it's only a late rhetorical flourish to the latest version of his regular opinion piece carrying his regular opinion. Still, responding to the 9/11 attacks, hoping to see a better life for Afghans than they enjoyed under the Taliban, the removal of a genocidal tyrant in Iraq - these weren't, any of them, reasons for war. The desire for war itself was all. It does rather simplify debate in the public realm: our reasons are like TOTAL, man; and yours... hey, where are yours? I can't see them anywhere.
