The prophecies of Hebrew scriptures were fulfilled (completed) in Christ. He fulfilled the law, so that we were no longer bound by it. That is the real key. We are Israel in a New Covenant - the old has past away. “The law is only a shadow of the good things that are coming . . “ (Heb. 10:1)
“For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance - now that he has died as a ransom to set them free from the sins committed under the first covenant. (Heb. 9:15). We are the Israel of the New Covenant - the Old Covenant will never return!
You will have to explain God’s unfulfilled promises to Israel and His broken covenant with Abraham and David, to hold to your claim... Let alone the promise about Israel in the Romans passage.
We are the Bride of Christ in the new covenant.
Israel is still Israel and will be restored someday.
We are the Israel of the New Covenant - the Old Covenant will never return!
Jeremiah
31:33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
31:34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
But this did not eliminate the land of Israel, it is still there two thousand years after the covenant was made.
When did God make a new covenant?
Did he make it to Israel or to the gentiles?
