I believe we are rather busy right now just trying to understand/mitigate our own vulnerabilities. As I read the papers, the most recent East Coast blackout wasn't caused by hackers, but could have been if the utilities incompetence hadn't caught up with them first. Recent grades issued for US cabinet agencies in cyber security were embarrasing to a number of top officials. Whatever their staffs may have thought they were doing, you can believe they are now trying to raise their Fs and Ds to a level more in keeping with their bosses' self image.

I assert that our side of the arms race is on at least tempory hold while reputations are repaired.
