The so-called "Jewish state" he endorsed was created in direct contradiction to Jewish law. No attempt has been made to bring the state under Jewish law.
A kingdom operating under Jewish law would be under the guidance of a king. This king should have been born Jewish, not a convert (though the son of a convert may be king). The king should establish his laws based on the Torah, the laws of the surrounding nations, and what prophets who have been demonstrated true instruct him.
The Sanhedrin should also be established. For this to occur, the respected authorities should assemble and unanimously select one man to be "nasi", or leader of the Sanhedrin. He should then immediately begin a search for 69 others to join him on the Sanhedrin. They should each be extremely knowledgeable in the laws of God and man, fluent in foreign languages, students of Tanakh and Talmud, and well-known for their piety, charity, and kindness. This body, the Sanhedrin, would have judicial and legislative powers, while the king would have executive powers and limited judicial and legislative authority.
The secular state which exists, however, does not have nor care to have these properties. I am not opposed to a movement to set up such a government, because I know that if it was true to its founding principles it would be fair and just to all citizens. It would allow shariah and existing Muslim courts to judge Muslim affairs within its borders; and it would allow Jews and Palestinians equal rights to the land.
Ezekiel 47:22 And it shall come to pass, that ye shall divide it by lot for an inheritance unto you and to the strangers that sojourn among you, who shall beget children among you; and they shall be unto you as the home-born among the children of Israel; they shall have inheritance with you among the tribes of Israel. 23 And it shall come to pass, that in what tribe the stranger sojourneth, there shall ye give him his inheritance, saith the Lord GOD.
This kingdom would also allow both Jews and Muslims the right to offer sacrifices to God on the Temple Mount. Under this government, Muslims and Jews could live in peace side by side in total fairness, without fear of harm. I call such a movement "kingdomist" to separate it from the secular Zionist movement and support it; though I do not support those who endorse genocide and racism in the name of such a government.
