Peter Huessy: Peter Huessy examines the fragile state of nuclear deterrence as Russia conducts drills for tactical nuclear weapons. He warns that the US is behind the eight ball regarding theater nuclear options, possessing only gravity bombs while Russia maintains thousands of short-range weapons. Huessy fears Putin may use these weapons for blackmail if he perceives a conventional loss in Ukraine. He advocates for the rapid modernization of the US nuclear triad, specifically calling for sea-launched cruise missiles to restore a credible deterrent against reckless adversaries. (6)
