The United States Congressional Budget Office estimates that the modernisation of the US nuclear arsenal will cost over US$400 billion between fiscal year 2015 and 2024. In response to current US plans, Dr James E. Doyle's new book Renewing America's Nuclear Arsenal: Options for the 21st Century demonstrates viable alternatives for modernising or replacing the United States’ full triad of air-, land- and sea-based nuclear weapons. These alternatives would allow the US to maintain deterrence at a lower cost, offer distinct advantages over the existing plan with regards to maintaining strategic stability vis-à-vis Russia and China, and upholding existing arms-control treaties, as well as supporting the global non-proliferation regime. Ultimately, Doyle provides options for ensuring the US nuclear force structure is better suited to the strategic environment of the 21st century.

Options for credible and reliable deterrence

The US need not replicate its Cold War triad to achieve credible and reliable deterrence, argues Dr James E. Doyle in the latest Adelphi book.
