Look around most Israeli cities and tell me – in your own layman’s opinion, whether you can truly claim the open peritzus, toevah, and entire secular nature (exemplified by much of the Army culture, for instance) is what rotzon hashem is r”l.
Definitely not the ratzon Hashem, so not what Rav Kook zt”l wanted or envisioned. Which is why, in hindsight, he clearly was wrong.
