Well, and I hope I get this right, according to him, they, the bad guys, whatever you want to call them, have been using looking glass, not necessarily to predict the future, but more to shape the future, based on our most probable reactions to many many events.  As of the time of ‘the event’, they are no longer able to shape the future, or get the desired outcomes that they want, and no matter what decision/s are made, regardless of the timeline/reality they are made in, they all lead to the same inevitable conclusion.
