Judah and Israel

I saw a plan to gradually divide the land into 2 states: Judah and Israel.
About 100 miles north of Tel Aviv, Israel.
And to the south, including Beit Shemesh, Bnei Brak, Jerusalem, the territories, the port of Ashdod, Eilat, Dimona, and its treasures for Judah.
Of course, the division is +- as most residents do, and individuals can move without harming their rights and property based on the constitution, values, education, etc.
Is this a good solution?
Every country will provide for itself, heal itself, and defend itself, and a Redeemer will come to Zion.
Whoever wants the Temple built, who will expel Arabs for the betterment of the world, will not work without the High Court and B'Tselem, etc.
And whoever wants to work will be able to eat, etc.
Each group will be able to live according to its own values.

Is this a good idea in the impossible situation we are in?
