Air Chief Marshal Lord Peach, the former Chair of NATO's Military Committee and architect of NATO's first new military strategy in 50 years, joins us to discuss the process of strategy-making in an Alliance context.

Lord Peach is the UK's most experienced officer, having served in key 4-star appointments, including as the UK's Chief of the Defence Staff (2016–18) and as the 32nd Chair of the NATO Military Committee (2018–21). He led the NATO military staffs through the creation of NATO's new Military Strategy and the family of plans that sit beneath it. He is now the UK's Special Envoy to the Balkans.

In conversation, he offers insights into the challenges and strengths of Alliance strategy-making in NATO. In his view, while NATO requires unanimity for the adoption of any new decision, this is not only possible, but vital. It is a strength rather than the weakness some, less familiar with the organisation, perceive it to be. However, once unanimously adopted, a strategy must cope with ambiguity and evolve before it is adapted to ever-changing, and inevitably ambiguous, circumstances.
