Time magazine Managing Editor Richard Stengel discussed a new Pentagon report that says "1 in 5 American servicemen and women who have been in Iraq are coming back with brain injuries." Stengel called it the "real toll" of the war, adding that "the legacy of that will last all of our lifetimes and it's incalculable."

In total, according to Stengel, "more than 250,000 people" are affected by "mild traumatic brain injuries" sustained in Iraq.
