Who appointed this as the “Jewish National Anthem”? Isn’t it currently used only by the reshoim who are self-hating Jews?
Judaism doesn’t really have a “National Anthem”. By definition, a national anthem is for a country – isn’t that what “national” means? Israel has a national anthem. Judaism doesn’t. It can be the anthem for a group (such as Neturei Karta), but it’s not a national anthem.
If ther e was an anthem for the Jewish people, I like Jewess’s idea – Shema is better suited.
