Young Joe, the Forgotten Kennedy (1977)

Joseph Kennedy Jr. was the eldest son of the Kennedy clan. He grew up having to deal with being humiliated and the prejudices of being an Irish Catholic. His father then tells him that the best way to get back at them is make a big impact in politics, in other words to one day be the President of the United States, and he wishes to do so. But first he has to survive World War II, and also he has to do something to make a splash like his brother, Jack, who was awarded the Navy and Marine Corps Medal in 1943 following his exploits commanding PT 109.
