ww1 was decided by UK and France vs Germany on the western front. By the time US finally got around the decisive grind was mostly over. Japan was left to do their own thing in the Pacific and mostly a sideshow

US contribution is in WW2 as the untouchable megafactory spamming everybody to death. protected by the largest oceans of the world fully invulnerable to bombing and invasions. no need to hog all the glory in delusions of grandeur
