The prince that breaks the covenant is NOT Jesus but a yet unknown false messiah that will deceive people -the very same false messiah that God sends as the great delusion
in 2Thessolonians 2
The text does not say the covenant is broken in Daniel 9:27.
The text says the covenant is "confirmed", or "strengthened".
You are changing the text to make your Two Peoples of God doctrine work.
You are taking the New Covenant found confirmed by the Messiah in Hebrews 8:6, and Hebrews 10:16-18, and Hebrews 12:22-24, and are converting it into a treaty or covenant broken by an antichrist not found in Daniel chapter 9, by adding a "gap" of time not mentioned by the angel Gabriel.
Your interpretation is antichrist, because you have taken something that belongs to Christ and have given it to a character not in the passage.
Daniel 9:27
(CJB) He will make a strong covenant with leaders for one week [of years]. For half of the week he will put a stop to the sacrifice and the grain offering. On the wing of detestable things the desolator will come and continue until the already decreed destruction is poured out on the desolator."
(ESV) And he shall make a strong covenant with many for one week, and for half of the week he shall put an end to sacrifice and offering. And on the wing of abominations shall come one who makes desolate, until the decreed end is poured out on the desolator."
(Geneva) And he shal confirme the couenant with many for one weeke: and in the middes of the weeke he shall cause the sacrifice and the oblation to cease, and for the ouerspreading of the abominations, he shall make it desolate, euen vntill the consummation determined shalbe powred vpon the desolate.
(GW) He will confirm his promise with many for one set of seven time periods. In the middle of the seven time periods, he will stop the sacrifices and food offerings. This will happen along with disgusting things that cause destruction until those time periods come to an end. It has been determined that this will happen to those who destroy the city."
(LITV-TSP) And he shall confirm a covenant with the many for one week. And in the middle of the week he shall cause the sacrifice and the offering to cease. And on a wing of the altar will be abominations that desolate, even until the end. And that which was decreed shall pour out on the desolator.
(KJV) And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.

(NKJV) Then he shall confirm a covenant with many for one week; But in the middle of the week He shall bring an end to sacrifice and offering. And on the wing of abominations shall be one who makes desolate, Even until the consummation, which is determined, Is poured out on the desolate."
(YLT) And he hath strengthened a covenant with many—one week, and in the midst of the week he causeth sacrifice and present to cease, and by the wing of abominations he is making desolate, even till the consummation, and that which is determined is poured on the desolate one.'
