Fullness of the Gentiles relates to the spreading of the gospel to the then known nations and is not a numerical number - Paul stated the gospel had been preached to every creature under heaven:
Col 1:23 If ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard, and which was preached to every creature which is under heaven; whereof I Paul am made a minister;
The fullness came in during Paul's time - then the end came.
Col 1:23 If ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard, and which was preached to every creature which is under heaven; whereof I Paul am made a minister;
The fullness came in during Paul's time - then the end came.
No, go back and read the context again. Rom 11:24-29.
V 26, "And so all Israel will be saved:" All Israel after the spirit.
--
V 28, "As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the Fathers' sakes."
The enemies spoken of here are Israel after the flesh that have rejected the gospel kingdom.
V 29, For the gifts and calling of God are without repentance."
But here Paul continues and says that even though they are enemies, they cannot, are unable, to undo what God has spoken about them.
The blessings of the kingdom and the gospel calling.

You say that the fullness of the gentiles was before 70 ad.
But it says that once the fullness of the gentiles has come in, that the blindness in part of Israel will end v25.
When Jerusalem was destroyed in 70 ad, Israel was still blinded in part, and it has continued into this modern era.
