So, how has the UK been left so poorly defended? Candid interviews with almost every real-life defence secretary since the end of the Cold War reveal all.   - Russia knows our weaknesses. But do you?   The Wargame from Sky News and Tortoise imagines how a Russian attack on the UK could play out – and invites real-life former ministers, military chiefs and other experts to figure out how to defend the country.   Written and presented by Sky News' security and defence editor, Deborah Haynes.  - Come to “The Wargame: Decoded” - our live event in January 2026.   It will put you in the mind of the people who took part. Deborah Haynes and some of our participants, including Sir Ben Wallace, Amber Rudd and Jack Straw, will talk through the decisions they made, the pressures they felt - and there’s chance to experience some of the key moments of the Game for yourself.  How would the UK respond in a crisis? And how prepared are we?  Join us for The Wargame: Decoded on January 29th in London (https://bac.org.uk/whats-on/the-wargame-decoded/) .
