Quality adverbs! Very good!
A number are Allied personnel who died while stationed in Washington during the First and Second World Wars. These people deserved honorable burial, but it would not have been feasible to send the bodies back to their native lands in time of war.
The next largest group, into which the Iraqui in question also falls, is comprised of foreign service personnel who were killed in air crashes along with Americans and whose remains are indistinguishable from those of their American comrades. During WWII, we apparently had an agreement with the Brits that when remains were intermingled in this fashion, they would be turned over for burial to the nation having the most service members aboard the aircraft. It is for this reason that British General Ord Wingate, leader of the famous Chindits in the Burma campaign, is actually buried at Arlington. I suspect there are Americans interred for the same reason in England.
I know space at Arlington is limited and will one day run out. However, I think our nation can and should be gracious enough to accord this brave Iraqui a decent burial beside his American comrades. We don't owe it to him. We owe it to ourselves to be big enough to accord him this honor.
