It was ... it could be construed that God was calling Patton home in order to make him available for another war. Patton always believed he was reincarnated from an earlier warrior who commanded in war.
His account of his memories from those earlier lives is a fascinating chapter in his autobiography. If one goes along with your idea, then in the next big war, can we expect to see his reincarnated self. In times of grave national crisis, do you expect to see American patriots reincarnated in this time to continue their fight for our country ? This makes interesting speculation if so. I think Ben Franklin has already reincarnated as Rush.
