For John, BLUF: Nucs are going to be around for a while, General Lee Butler and President Obama notwithstanding. Nothing to see here; just move along.
It seems to me that President V Putin has done more for nuclear proliferation than anyone since Harry S Truman. Think Budapest Memorandum on Security Assurances. I just can't imagine Iran or north Korea, or even Japan or Ukraine not thinking about how important nuclear weapons are to their own territorial integrity. Give them up and what do you get in return? At this point there are much bigger fish to fry than the deluded♠ Edward Snowden, who is being tagged with impacting our nuclear counter-proliferation intelligence efforts by a writer at The Wall Street Journal.
