Is the threat of nuclear terrorism real? Listen to Graham Allison, Martha Crenshaw, David Holloway and Joe Martz as they investigate the evidence with myself and selected Stanford students. What would be the consequences of a nuclear terror attack? The scenario is difficult to imagine, but Alex Wellerstein and Lynn Eden help me and our students understand just what could happen if the worst case occurs, and how we can work to limit the damage. What can we do to prevent or mitigate this risk? Participate as I explore this crucial question with the help of Stephen Flynn, Rachel Bronson, Valerie Plame Wilson, Ellen Tauscher and Jeffrey Lewis.
