So you are going to make your choice for president based on a speech reference. Most likely US forces visited Auschwitz after the Russians liberated it from the Nazi and his uncle was a part of that team. It doesn't change the moral of the story that his uncle was traumatized from what he saw after he came back to US.
The second quote about the dead soldiers was a metaphore which everyone knows is not real but is used to describe someone feelings.
I am a republican before you start any tirades against me.
