Former senior NATO figure and arms control negotiator Rose Gottemoeller delivered the 2025 Owen Harries Lecture on Monday 24 March in Sydney. She reflected on a new era of nuclear weapons competition.

China is rapidly growing and modernising its nuclear arsenal while Russia has used nuclear sabre-rattling in its war in Ukraine. Rose Gottemoeller explores the advent of an unprecedented situation — three nuclear peers — and the implications for the United States and its allies. She will also discuss the possibilities for nuclear restraint and arms control.
