How Many Times Over Must We Be Able to Destroy the World to Prove We are Not Wimps?

America’s nuclear weapons submarine fleet has the capability to produce something like 40,000 Hiroshimas.  But it is just one leg in our nuclear forces.  What possible reason, asks our guest Joe Cirincione of the Quincy Institute, for possessing that kind of destructive force?  For giving the president sole authority to launch a first strike?  We discuss these and other nuclear modernization choices facing the Biden Administraiton with Joe as well regulars David Sanger of the New York Times, Kori Schake of the American Enterprise Institute and Rosa Brooks of Georgetown Law School.  We also take time to reflect on the legacy of the late General Colin Powell.  Join us.
