Rav Shlomo Aviner
Hallel on Yom Ha'atzmaut
Question: Should Hallel be said with a beracha
on Yom Ha'atzmaut and on Yom Yerushalayim?
B. We were still enslaved to Achashverosh and we cannot say "Praise, servants of Hashem".
C. Reading the Megillah is in place of Hallel.
The Meiri and the Chid"a are of the same opinion.
The Rogotchover explains that this is the reason why Chizkiyahu, King of Yehuda, did not
say praise after Sancheriv's fall, since the miracle did not involve Klal Yisrael, as a
number of tribes had already been exiled. If so, it is apparently not possible to say
Hallel with a beracha except for a miracle which occurred for the entire nation and not
only for the inhabitants of Zion.
Rambam emphasizes that all of the festivals exist only in merit of the fact that there are Jews in Eretz Yisrael, and if there would be a situation in which there were no Jews there at all, the whole of the order of the festivals would collapse, something which could never happen, chas ve'shalom, because of the divine promise. Chatam Sofer adds, "Even simple people such as vine-growers and farmers". Rambam also explains that theoretically, an agreement to renew "Semicha" and the Sanhedrin would be effective, "As long as it happened in Eretz Yisrael".
We also have a proof from Chanukah. At the time of the Hasmonean victory, most of the Jews were not in Israel, yet they still said Hallel. There are those who reject this, claiming that Chanukah saved the entire nation because of the victory against the Hellenists and the dedication of the Temple, and both of these concern Klal Yisrael. The reply to this is that the establishment of an Israeli state also concerns Klal Yisrael and not only those who live in Israel!
Chazal define, "There is no difference between this worldand the days of Mashiach except for the servitude to the nations". In this world, the nations of the world tell us what to do, and in the days of Mashiach, we decide for ourselves. If so, does the establishment of the state has something to do with the days of Mashiach or not? Does it concern Klal Yisrael or not? It most certainly does!
