They are lucky that they have books in Arabic. They are lucky they live in Israel. I am almost positive that the Ministry of Education will quickly fix this problem and probably come out with a whole new edition of Arab-Israeli textbooks that glorify the "Palestinian Peoople" (of course Jews not included in Palestinian History). But I just hope that these "mistakes" aren't just sill ones like calling an airconditioner a "Mazgan" rather than "Mekayyef Hawa". Most Arab Israelis, and probably West Bank Palestinians for that matter call it a "Mazgan" in any case, so it's not really a mistake.
