Well, Mueller hasn't released his report to the authority who vets it for classified info. So Mueller's the one to blame for this guy's disappointment. Donald Trump is a Baby Boomer, and by definition could not have fought the Nazis or Japan. OTOH, his father built housing for the US military during WW2, which contributed to the US war effort. Trump senior also POed some in NYC by being willing to rent his properties to Jewish people at a time when many property owners would not. Those aspects of life were part of the context in which President Trump was raised.
