That's actually not the half of it. He served in the German infantry, was captured by American troops and spent some time in a POW camp. He claims he was ill and could not fulfill his role in the infantry to his full capabilities and also claims he deserted the Wehrmacht before the yanks arrived, but was captured anyway. Sure Sure. Either way they didn't call him Benedict for nothing.
What would you have done in his place, at that time in that place?
To do anything other than join up, was tantamount to wearing a Crucifix and chanting 'death to all Muslims' in a Taliban stronghold today.
