Just Emes:
Your sources are not fitting your screen name. You are using Zionist propaganda as a basis for your statements. Read what really happened in 1948 and then try again. The Zionists had no reason other than Zionism to attempt to take Yerushalayim in 1948. This was a clear violation of shelo yaalu biChomah as they were not given Yerushalayim.
Besides, the entire Zionist ascension was clearly anything but peaceful; it was definitely not biShalom. If you really want to get technical about who did and did not give permission, the Arabs of Mandatory Palestine were not members of the UN and they very much did not agree with Zionist aspirations. The UN, even if all its members agree, has no power to nullify the oaths.
Regardless, this all only addresses the shelo yaalu biChomah oath. The political rule in Eretz Yisrael is a separate violation of not forcing an early end to the galus.
Regarding Rav Moshe, even the Zionists admit that he was against flying the Israeli flag, both inside and outside shul and he called the founders of the State wicked, etc. and that if the Israeli flag were to be considered “holy” by Zionists then it would be like a keili of A”Z.
