Jesus cursed Israel and left them desolate, why wouldn't that be exactly who Daniel 9 is talking about? I mean think about, that's exactly what happened, they committed the greatest abomination that could ever be committed, they killed their Messiah. And the Messiah obliterated them for it in AD 70.
So the Anti-Christ desolates the Jews during the 70th week, but they were also left desolate in AD 70 in that God forsook them for 2000 some odd years up until 1948.
