That is false. To fulfil the Great Commission it was simply necessary to preach the Gospel to all the Jews in Jerusalem, Judea, and Samaria. And this was indeed accomplished as we can see in the book of Acts. Not all believed, but all did hear the Gospel.
Since the outset of your posting you have shown that you really do not understand the Great Commission, and how it was given to the apostles and now it is still given to the Church (the Body of Christ) until the Second Coming of Christ.
Many prophecies in the Kingdom program for Israel are dependent on the Jewish nation accepting their King before they can happen. I would think all the Jews then, who have been taught the OT since they were young, would have understood them.
Jeremiah 23:5 KJV Behold, the days come, saith the Lord, that I will raise unto David a righteous Branch, and
a King shall reign and prosper, and shall execute judgment and justice in the earth.
6 In his days Judah shall be saved, and Israel shall dwell safely: and this is his name whereby he shall be called, The Lord Our Righteousness.
Luke 1 NLT 30 “Don’t be afraid, Mary,” the angel told her, “for you have found favor with God! 31 You will conceive and give birth to a son, and you will name him Jesus. 32 He will be very great and will be called the Son of the Most High.
The Lord God will give him the throne of his ancestor David. 33 And he will reign over Israel[c] forever; his Kingdom will never end!”
Zechariah 8 explains
3 “Thus says the Lord: ‘I will return to Zion, And dwell in the midst of Jerusalem. Jerusalem shall be called the City of Truth, The Mountain of the Lord of hosts, The Holy Mountain.’
Later on, in the chapter in Zechariah 8:20-23 New Living Translation (NLT)
20 “This is what the Lord of Heaven’s Armies says:
People from nations and cities around the world will travel to Jerusalem. 21 The people of one city will say to the people of another, ‘Come with us to Jerusalem to ask the Lord to bless us. Let’s worship the Lord of Heaven’s Armies. I’m determined to go.’ 22 Many peoples and powerful nations will come to Jerusalem to seek the Lord of Heaven’s Armies and to ask for his blessing. 23 “This is what the Lord of Heaven’s Armies says:
In those days ten men from different nations and languages of the world will clutch at the sleeve of one Jew. And they will say, ‘Please let us walk with you, for we have heard that God is with you.’”
A similar prophecy was given in Micah Chapter 4 (NLT)
In the last days, the mountain of the Lord’s house will be the highest of all—the most important place on earth. It will be raised above the other hills, and
people from all over the world will stream there to worship.
2
People from many nations will come and say, “Come, let us go up to the mountain of the Lord, to the house of Jacob’s God. There he will teach us his ways, and we will walk in his paths.” For the Lord’s teaching will go out from Zion; his word will go out from Jerusalem.
Finally, the same prophecy was given in the book of Isaiah chapter 2:2
In the last days, the mountain of the Lord’s house will be the highest of all—the most important place on earth.
It will be raised above the other hills, and people from all over the world will stream there to worship.
So, based on these 3 accounts, the timeline was supposed to be Jews are to be saved first, once they accept Jesus has the Messiah, then the Kingdom will be established in Jerusalem and the Jews will then be priests spreading that blessings to all the Gentiles.
Finally, when Jesus was on Earth, he also said this to the Samaritan woman
John 4:22 New Living Translation (NLT)
22 You Samaritans know very little about the one you worship, while we Jews know all about him,
for salvation comes through the Jews.
