That was done by the UK and the United States. We felt guilty (we were) so we educated them all. The Palestinians were the best educated group in the middle east. The rest of the middle east didn't approve of all the lern'in so the Palestinians were pariahed throughout the middle east. Always wondered about that one.
OH, almost forgot. We did that because the Jews had a serious terrorist operation going on and we, (UK and US) wanted that over so we gave up to the Jewish terrorists and gave them Palestine. The Palestinians never received any payment for what we gave to the Jews. Always wondered about that one too.
There is a movie about the Jewish Terrorists (they are heroic in this one): https://www.imdb.com/title/tt0053804/
