Fifteen and a half years after our enthusiastic support for the US-led military intervention in Iraq, we're going back again. This time it's with a ship, a plane and a couple of hundred personnel to join another coalition of the willing, this time Donald Trump and Boris Johnson's armada targeting Iran.

Various names are being floated as other possible participants in the latest Coalition, without, one hopes, the embarrassment of being added by mistake. Of course, as the "forever war" dictates, we never really ended the Iraq venture. We've been training or bombing in Iraq ever since. We've spent over $1.3 billion since 2014 going after the direct result of our Iraq intervention, Islamic State -- with the occasional, and of course highly regrettable, deaths of innocents.
