Note: These are the schools run by the U.N. in the Palestinian territories of Gaza, Judaea and Samaria. The United Nations. And they are written by the Palestinian Ministry of Education, part of the Palestinian Authority which signed the Oslo Accords and officially recognizes Israel, not by Hamas.
So while the U.N. and the U.S. admonish Israel for expanding the settlements, Palestinian children are raised and educated by the U.N. to believe that the State of Israel itself is completely illegitimate.
This is not simply "anti-Israel bias". This is not pursuing a "Two State Solution". This is anti-Semitic bullshit.
