The ISIS campaign is utterly amorphous and open-ended at this point — exactly the kind of potentially crippling government program Republicans usually want to slash. It could last more than three years (and that’s what they’re saying at the outset); the cost is estimated by some to be around $15 billion a year, but no one really knows. The last phase of the same war cost, when all was said and done, something close to $1.5 trillion – and our current travails prove that this was one government program that clearly failed to achieve its core original objectives, and vastly exceeded its original projected costs.
If this were a massive $1.5 trillion infrastructure project for the homeland, we’d be having hearing after hearing on how ineffective and crony-ridden it is; there would be government reports on its cost-benefit balance; there would be calls to end it tout court. But a massive government program that can be seen as a form of welfare dependency for the actual countries — Turkey, Iran, Jordan, Kurdistan — facing the crisis gets almost no scrutiny at all.
Don't worry, there's always money for war. Schools, health care, infrastructure, Social Security, not so much.
