Yes, friend, I remember that during WWII allied casualties were never reported.
Your comparison doesn't work. World War II was a war that was fought for clear objectives. This is a different kind of war which lacks these clear objectives. It is a Wilsonian war to create a unitary/nation state in a multi-ethnic, multi-religiouis medieval stew.
Also from a purely practical standpoint if this slow bleed continues into next year the American people will not stand for it.
Pretending otherwise will not change this.
