From the article:
"Hagel ordered the reviews of the nuclear forces earlier this year after a string of scandals: incidents that involved lapses in security, cheating on tests and other failures."
We've spent at lot over the past few years quietly securing nukes among the former Soviet republics. Hagel is asking that we refocus on what is troubling about our own nuclear security measures.
If you think that 'we're fine, it the Russians we need to worry about', please take the trouble to seek out and watch the film Countdown to Zero" It'll change your mind (as well as giving you nightmares).
Thanks, Omaha Steve, for posting this.
