Zionists in Palestine forbade the Yiddish. Every printed material in Yiddish in years before creation of Israel was destroyed and every printing house was blown up. Zionists wanted to create completely new identity in region of Middle East because European Ashkenazi Jews who created the State of Israel and still are in power since 1948 have nothing in common with region of the Middle East. They are not indigenous at all. Not a single Israeli prime minister was born outside of Poland or Ukraine or their parents were born there. Some of them hebraized their last names to make them more fit for the Middle East. Benzion Mileikowsky, father of the acting Israeli prime minister when came into Palestine changed his last name into Netanyahu. Golda Mabovich Meyerson born in Kyiv, Ukraine, after her husband died moved from the United States to Israel and changed her last name into Meir and became Golda Meir, David Ben Gurion was born as David Grün in Poland.
Israel is the only country in the world which lobbies for its existence and its false narrative. They invest a lot in propaganda or hasbara. It frustrates them so badly after 75 years more and more people in the world see for themselves the Zionist narrative is a deception. Zionists are professional manipulators.
The only thing that makes them even more angry is that Palestinians refuse to forget and surrender after 75 years.
