I could be entirely wrong and I don’t meet to be disrespectful to those who hold a more “traditional view” it’s just I look at Tisha B’av through a different lenses. We can agree that Tisha B’av deals with remembering the horrible destruction of the temple and the expulsion of the Jewish people from Jerusalem and Israel as a whole. The difference happens after 1967 and how we in the faith should observe this remembrance now. For today Jerusalem is a thriving faithful city that miraculously has survived many attacks from all different enemies. I truly believe G-D has allowed the people of the Jewish faith the fortitude to keep this city in their control against all odds and for that we must be grateful. Yes, we don’t yet have the “Holy Temple” and that is a great loss but the victories we have had can’t be ignored. Therefore I believe Tish B’Av today should by observed with a minor fast such as giving up a particular food in remembrance of that loss but remembering the blessing as well that we continue to see in the holy city we call Jerusalem.
