Old news, I believe. It's also quite a ways from being workable. Although, somebody with a lot of brass did mention it today in an assessment of China's intentions.
More important, I'm becoming more of the opinion that any war with China won't be particularly conventional. Conventional ballistic missiles aren't as spooky as their ASAT and hacking efforts. The effort to deal with carriers isn't worth the payoff when fucking up our GPS network = game over. Our increasing dependence on computers would make a top-down attack absolutely devastating.
