So they are not factual errors, merely disagreements in interpretation.
If an omniscient God chose the Jews before the foundation of the world, then He would have known that He planned to reserve a small corner of the earth for them. I'll grant you that the modern state of Israel is secular, but I argue that by the time of the exile of Israel and then Judah both those states were pretty secular as well.
It is quite possible, in fact it fits with Scripture, that God merely intended to give them the land for a time as a typological representation that one day His wpopel woul dinherit the whole earth. That is the undeniable perspective of the New Testament. See Matthew 5:5, Romans 4:13, and Hebrews 11:9,10,16.
The typological day is past. The new covenant has arrived when the new covenant people, Jews and gentiles together, are receiving the promise by virtue of their faith in the Lord Jesus Christ and children of Abraham (Gal. 3:28,29).
