Buried in this article is a statement about the practicality of Nuclear Weapons for maintaining the peace in this post-Soviet world:
""We realize we are trying to deter the actions of non-state actors who don't have population centers, don't care about dying," Gration says, explaining why nuclear stockpiles have outlived their usefulness. "But these weapons can get into the wrong hands." Moreover, eliminating nukes would actually increase American military superiority. (We have a far more powerful conventional force than any other country on the planet.)"
It's very interesting, and I've argued peace through nukes perhaps a dozen times on this blog, so I'll have to give it more thought soon. For now I'll leave you with that, and with a brilliant article worth reading for its own merits.
