I went to school in Abu Dhabi in the 80’s and recall all the maps on the walls either having Israel scratched out or depicting the whole area as Palestine. I recall customs at the airport going through one’s books to make sure there were no maps referencing Israel. I don’t see how this would shock anyone as this has been the standard my entire life.
It is a bit different that they changed the borders. when I was there (83 I think) the maps did show something there, but it certainly wasn’t called Israel.
