I rented both Matrix Reloaded and Animatrix this saturday and the Washowski brothers messsed up! Bad!

In the movies, they use an electromagnetic pulse to desable the sentinels right? And in the Animatrix, thay say that the humans bombed the robot city with nuclear weapons but the heat and radiation had no effect on the robots... UHUH?? What else does a nuclear blast cause? A BIG ASS ELECTROMAGNETIC PULSE!! DUH.
