Indeed, though, this is not the anthem of the Jewish people – it is the anthem of bnei Torah in Eretz Yisroel and a protest song.
The anthem of the Jewish people indeed could be any one of a number of psukim from Tehillim that can be put to music; the motto of the Jewish people is Shma…echod.
For the anthem of the frum community in NY, I humbly propose Lipa’s GELT song :-)! Then again, except that it is in Yiddish and acheinu bnei Yisroel who are not of European origin could not relate to it, Sheloi Asoni Goy from A Poshuter Yid could be the anthem of the Jewish nation….at least on Purim!
