minato wont kno witch 1 is the real him that makes ur argument false. an if minato knos wats good for him he will stay away from the sharingan he dont want that again lolLol that is'nt even a valid argument, Iruka is still in the show, you think its cuz he's tough? SO6P is'nt in the show, but he was the toughest in history. Your argument is false.
And IF he has a shaodw clone, Minato will be able to sense that there are 2 people in that area using his jutsu, he will attack the real Itachi.
