The May/June digital journal is now available

All major nuclear powers have modernization programs in progress, with the US modernization program slated to bring profound changes to all three legs of the nuclear triad. At the same time, the Trump administration has launched a new nuclear posture review, pushing for a large buildup in conventional forces. This special issue on nuclear modernization examines the effects any new buildup of conventional forces could have on the financing of US nuclear modernization, the political coalitions that support it, and overall strategic stability of the effort.

You'll also get free access to an interview with environmentalist and entrepreneur Paul Hawken about Project Drawdown, “the most comprehensive plan ever proposed to reverse global warming.” We've also got great coverage of the UN nuclear weapons ban treaty, a thorough examination of DARPA in the age of hybrid war, the closing of Japan's Monju fast breeder reactor, and a review of Uncommon Cause: A Life at Odds with Convention, a memoir from General George Lee Butler, the man who spearheaded a drastic realignment of post-Cold War nuclear forces.
