That's like asking, "should the United States have free speech?" But it also has other implications as well. If our enemies have networks, and ours our disabled, how in the world are we going to "win"? How do you even "win" a "cyber war"?
You can prevent "cyber warfare" by disconnecting sensitive stuff. You don't need to kill Wikipedia or my blog because there's not much warfare you can really wage with pages that aren't sensitive in nature. How is an enemy going to abuse Remember The Milk or Reddit to the extent that it cripples our national security? So a kill switch is not only stupidly impractical because it makes us more disorganized and disconnected than an enemy, but also because it's strictly unconstitutional.
A better question: is there a sane justification for it?
