"Clark, you bastard. You let them do it. I always knew you would. Maybe during breaks between police actions, one of your military friends told you what an electromagnetic pulse is. And maybe you listened, Clark. All you need to generate the pulse is the detonation of a few dozen nuclear warheads. That, or a special kind of nuke that both sides have been trying to develop... Yes, Clark. Both sides. The American name for it is Coldbringer. It is designed to cause maximum damage to the environment -- all the while sparing the industrial sites your friends regard so highly. Since my own atoms aren't bouncing around the stratosphere -- since Gotham City squats like a great black graveyard -- since Wayne Manor's emergency generator hasn't kicked in -- and Robin's watch has stopped -- I'll assume Russia has taken the lead in the arms race. I keep track of these things, Clark. One of us had to."
