This little semantic change has major implications, this isn't just a statement about Gush Katif, this is Israel has never been the "dawn of the redemption". Nothing Israel has done up till now, for R' Shear-Yashuv, has been part of the redemptive process. That a major theological statement. One that I don't think is shared by many of the Da'ati Leumi.
I think R' Shlomo Aviner's statement here sums it up:
But Rabbi Shlomo Aviner of Beit-El refuses to give up. He addressed these teenagers in a brief article entitled: "I say a prayer for the state's wellbeing." Aviner wrote that despite the state's desecration of the Sabbath and the sanctity of the land, he would never stop praying for its wellbeing, "because this is my state. I have no other, and I love it the way it is." And though the government causes him great distress, it is his government and he will "continue to pray for it with all my heart," and take pride in the fact that the Jewish people governs itself and is no longer subject to others.I hope that last sentence is wrong. This is still Israel, still the reishit smichat geulateinu, if Gush Katif was supposed to be part of the State then sometime in the future it will become re-inhabited when the time is right. So, enjoy your Yom Ha'atzmaut (but please don't forget about Yom HaZikaron either).
The vast majority of religious Zionists are still of Aviner's mind. Even the Yesha rabbis' committee has called for celebrating Independence Day, adding that the state's very existence is a central pillar in the redemption process. But for many the celebrations will not be wholehearted.
