Avi:
?? ???? ???? ????, When our true redeemer comes forth, when Hashem will effect the true geulah, then we will celebrate. If it’s proven then that any of these ‘chagim’ instituted by the bareheaded, are indeed installments of the awaited geulah, perhaps we will celebrate them as well. Until then, let’s not lose focus. Most clearheaded think it’s only getting in the way of the true geulah. (I can guarantee you, Mashiach won’t be bareheadedly declaring statehood “?? ????? ??? ????? etc.” five minutes to shkia erev shabbos)
The only meaning to these days I can think of is such hakaras hatov to Hashem. How he showers His nation with good DESPITE the great chilul Hashem from the armies, the not-yet-religious, the mass chilul shabbos ect. How he crowns success upon armies that DON’T EVEN CARE TO KNOW HIM, just because He is their Father, Great Shield. How he protects His people DESPITE THE IDF, because He so cares for each of us.
Now that is cause for celebration.
