Wars cost too much.
That’s really not a surprise. The surprise is how much more they cost than we’ve been told.
It might help to think of the nation’s post-9/11 wars in Afghanistan and Iraq like a pair of icebergs. The Pentagon tells us how much we’ve each paid for the wars. But that only tells us how much of those icebergs we can see above the waves. While it includes totals for war fighting, it doesn’t track the Pentagon’s bigger war budget, interest paid on money we’ve borrowed to fight the wars, veterans’ care, and other ancillary costs. There’s a whole lot more hidden beneath the waves. The real issue isn’t whether the cost of war is high; the issue is why the U.S. government keeps under-estimating it, and why U.S. citizens and taxpayers keep tolerating it.
