The hypocrisy of wishing Jews a peaceful Tisha B’Av while relentlessly attacking the Jewish state is hard to miss. It is yet another example of Mayor Mamdani gaslighting the Jewish community. Tisha B’Av isn’t just about mourning the destruction of the First and Second Temples in Jerusalem. It’s a reminder of what Jewish statelessness has meant throughout history: exile, persecution and slaughter. It is the day the Jews were expelled from England in 1290, from Spain in 1492, the day the Nazis began the Great Deportation from the Warsaw Ghetto - sending more than 265,000 Jews to their deaths at the Treblinka extermination camp over the course of two months. These and so many other calamities. Extending holiday wishes while opposing the Jewish people’s sovereignty in their ancestral homeland misses the historical lesson that lies at the heart of Tish B’Av.
