This seems like a pretty effective ad to me:
It’s worth saying that the sort of cost estimates you see in this ad, while accurate, are substantial under-estimates of the real monetary cost of the war. Soldiers injured during wartime will, for example, continue to receive medical treatment for their wounds for years if not decades. Somewhat similarly, a lot of the equipment that gets damaged or destroyed in Iraq is either being replaced with money that doesn’t come out of the Iraq-designed funds or else hasn’t actually been replaced yet but will need to be replaced down the road.
The fiscal cost of the war isn’t the most important aspect by any means, but it is a good shorthand way of understanding why it is that we can’t just keep doing this out of a vague hope of rolling snake eyes thirty times in a row.
