The cost of US wars
We’ve taken the estimates and created a handy graphic.
There's a snapshot on your left. You can also look at the full graphic -- along with the option to view war costs by size of GDP. (We created the graphic using a free Web site from IBM called ManyEyes.)
The report notes that the estimates are likely an undercount:"All estimates are of the costs of military operations only and do not include costs of veterans benefits, interest paid for borrowing money to finance wars, or assistance to allies."
