When the Chief Rabbi, Sir Jonathan Sacks, brought out his new edition of the Singer's Siddur, the main prayer book for Orthodox congregations in the UK, two years ago, it was the first to include a section for Yom Ha'atzmaut, Israel Independence Day.
When it comes to Hallel, the traditional festive prayers of praise, the siddur notes that it is recited "in most communities" - and that there are "varying customs: some say it with, some without, the opening and concluding blessings".
Perhaps a half-Hallel with berachot is the most appropriate for Yom Ha'atzmaut.
