Pentagon to use Nukes against Hackers?

What’s the latest weapon in the Cyber Arms race?  Nuclear bombs, apparently. http://www.acq.osd.mil/dsb/reports/ResilientMilitarySystems.CyberThreat.pdf Okay, let’s not over react.  The report says that the U.S. would only use nukes under extreme circumstances.  Hopefully that doesn’t mean viagra related SPAM. Seems like, if anything, maybe an EMP would be a better alternative?
