Answer

Do you intend to keep repeating this hair-splitting argument in more questions? I’ll start deleting them.
It’s quite amazing that the place where the most Jews were killed is exactly the place where the most Jews are. What a remarkable thing! You remind me of the sermon I gave on Purim when I was the Purim rabbi in the yeshiva. I said I had found an unbelievable discovery: that the minimal skip of the word Esther in the Hebrew Bible is found precisely in… the Book of Esther. A skip of 1.
And seriously, this is protection against possible pogroms. The fact that they haven’t happened doesn’t mean they won’t happen. And in addition, the fact that they haven’t happened may also be because the state exists. Something like the claim against the Vilna Gaon, who came out against Hasidism, and people argued that he was mistaken, since in the end the Hasidim did not abandon commitment to Jewish law and Torah. His students’ answer is of course: that itself happened thanks to the Vilna Gaon’s struggle against them. Reflect carefully on that.
And finally, the purpose of establishing a state is to give the Jewish people a home. The refuge is an additional matter. This people had no home until the establishment of the state. Like in that survey of intellectuals in the 1950s, when foreign journalists went around asking various intellectuals why they were Zionists. When they asked Leibowitz, he answered: because we were sick of gentile rule.
By the way, the Haredim also are not abandoning this place en masse despite the terrible dangers. Though for them there aren’t really so many dangers, since all the losses in wars and in the army are irrelevant to them. Splendid consistency.
