Donovan’s wikipage:
http://en.wikipedia.org/wiki/William_Joseph_Donovan
Donovan was the head of the OSS and was awarded a Medal of Honor. If he was willing to sign his name to a certificate that John Wayne served honorably as a member of the OSS, that is good enough for me.
When one thinks of the OSS isn't the image that of super secret spies working behind enemy lines? Instead of doing that, Wayne starred in some of John Ford's OSS training films. Kinda falls flat at that point, but I suppose that's good enough for you. Low standards, I guess.
But go ahead, admire someone like that.
