According to this source, the uncle is still alive, so it's just a matter of asking him.
As I noted earlier, I think the way he used it is a bigger problem. Implying that large numbers of American soldiers become mentally ill, thus all must be evaluated, based on the uncles 6 month long breakdown during which he consigned himself to the attic. I feel sorry for the man having to have these issues raised in his old age.
He more then likely is a Typical White Person ala The Obamao’s Grandmother....
How shameful that the man does not even know what his family did in WWII, especially during the Liberation of the Death and Work Camps....
