Is there nuclear fallout in our future?

Anyone interested in nuclear proliferation issues (or is wondering whether or not to buy a bottle of potassium iodide just in case) should read this excellent feature article by Barton Gellman and Dafna Linzer that appeared in today's WaPo.

Here is the money quote from Robert L. Gallucci, former arms control official and currently Dean of the Georgetown School of Foreign Service and consultant to the CIA and DOE on proliferation issues:

If tomorrow morning we lost a city, who of us could have said we didn't know how this could happen? I haven't felt like this in all the years I've been in government or the nine since I've been [out]. I am -- I don't want to say scared, because that's not what I want to project, but I am deeply concerned for my family and for all Americans.

(In case you're wondering, yes, I've purchased two bottles of potassium iodide (one for home, one for the car). You can get yours here.)
