That's pure supposition...Daniel 9:26 doesn't say that at all!
Dan 9:26
And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof [shall be] with a flood, and unto the end of the war desolations are determined.

“And after the sixty-two weeks, the anointed one will be cut off, and he will be no more, and the people of the coming monarch will destroy the city and the Sanctuary, and his end will come about by inundation, and until the end of the war, it will be cut off into desolation.”
...The anointed one will be cut off: Agrippa, the king of Judea, who was ruling at the time of the destruction, will be slain...
...and the people of the coming monarch will destroy: [The monarch who will come] upon them. That is Titus and his armies...
...and his end will come about by inundation: And his end will be damnation and destruction, for He will inundate the power of his kingdom through the Messiah, and until the end of the wars of Gog the city will exist...
and the people of the prince that shall come shall destroy the city and the sanctuary..
Who destroyed the city and sanctuary of Jerusalem in 70 A.D.?
that will be the people of the Anti Christ.
