The Government of Israel is secular. One can argue it’s not even Jewish (an organization run by Jews but not according to halachah is probably not considered a Jewish organization- like a Reform Temple). But it’s still better than any other secular non-Jewish government would be. While many of the members don’t follow halachah, and the laws are not based on the Shulchan Aruch, many meta-communal laws are based on halachah- like Geirus and Marriage- which makes things a lot less complicated for frum Jews. And while it is not illegal to violate Shabbos, to my knowledge, the government itself doesn’t run on Shabbos, which probably limits a lot of the chilul Shabbos.
Not to mention that no other secular/non Jewish government over Eretz Yisroel would give as much money to Yeshivos as the current government of Israel does, and no other secular/non Jewish government would give all Jews a blanket right of return which facilitates massive fulfillment of Yishuv Eretz Yisroel.
Are there problems with the government? Of course. Is the secular government of Israel considered Jewish sovergnty over Eretz Yisroel? I have no idea. Does the government itself have any halachik or hashkafik significance? Who knows. But having this government over the Land of Israel, is better than any other Non Jewish government over the Land of Israel. And I think some of us need to take a step back sometimes and appreciate how great we have it.
