British Prime Minister Boris Johnson announced his government is lifting the cap on its nuclear stockpile, increasing the number of Trident nuclear warheads by over 40%. The move ends three decades of gradual nuclear disarmament.

Meanwhile, in the U.S., a new report by the Federation of American Scientists says plans to build a new $100 billion nuclear missile are being driven by industry lobbying and politicians whose states will economically benefit from the project, despite objections from military and civilian leaders around the cost and lack of security relevance for the “Cold War-era weapon.” The cost of building and maintaining the Ground-Based Strategic Deterrent, or GBSD, which would be built by Northrop Grumman with help from Lockheed Martin and others, would swell to $264 billion over the coming decades.
