Shotgun,
The problem with using 70CE as the fulfillment is that you are mixing a symbolic figure in Daniel with a literal Jerusalem. And our Lord did not return at that time which is the most important part of this prophecy. Events only seemed to fit the text but the prophecy in Daniel ends when Daniel stands up and those asleep in the ground awake. Such use of Daniel's prophecy actually prevents any application to the Romans in their day and 70CE in particular.
Joseph.
