I found this (see WSJ link below) a remarkable story. Generally speaking, when thinking of the costs of war, I don't think of tallying the years of "after war" costs... moreover, I certainly didn't think of how expensive it really was!

It's a long, but great read that addresses more than just costs. I recommend it.

Spouses, parents and children of deceased veterans from World War II, Korea, Vietnam, Kuwait, Iraq and Afghanistan received $6.7 billion in the 2013 fiscal year that ended Sept. 30. Payments are based on financial need, any disabilities, and whether the veteran's death was tied to military service.
