In Jeremiah 30... The word that came to Jeremiah from the Lord : “Thus says the Lord , the God of Israel: Write in a book all the words that I have spoken to you. For behold, days are coming, declares the Lord , when I will restore the fortunes of my people, Israel and Judah, says the Lord , and I will bring them back to the land that I gave to their fathers, and they shall take possession of it.”
The UN did that, not Jehovah. They don't have all the land they had. Also, it's a secular nation with many Muslims and Christians living there.
In Amos 9... I will restore the fortunes of my people Israel, and they shall rebuild the ruined cities and inhabit them; they shall plant vineyards and drink their wine, and they shall make gardens and eat their fruit. I will plant them on their land, and they shall never again be uprooted out of the land that I have given them,” says the Lord your God.
Well, clearly that one can't be true, one day the sun will expand and turn everything on it to a crisp, so the "never" on that one fails.
In Isaiah 11... He will raise a signal for the nations and will assemble the banished of Israel, and gather the dispersed of Judah from the four corners of the earth.
Not all of the dispersed are there. Also, the UN re-established the nation of Israel, not Jehovah.
