I hope that my memory regarding Nusach Ashkenaz as practiced in Israel is correct, here.
For Nusach Ashkenaz, one of the main differences between Israel and the diaspora that I recall is including En K-elo-heinu / Pitum at the end of Shacharit. (I'm not referring to somewhat "smaller" changes such as to the ending of some words (See this question) and having "Morid Hatal" before the 2nd Amidah bracha.)
Why are these prayers that are near the end of Shacharit excluded outside Israel?
