Maurice Rose was an American armoured divisional commander during World War II and widely regarded as one of the most talented (in addition to being one of the most highly ranked Jews in the US Army).

Would he have played a significant role during the Korean War (assuming butterflies don't interefere) or would he have sought a role in politics?
