What would a ceasefire in Ukraine mean for Europe and the world?
8 September 2026, 1:00 pm – 2:00 pm
Location: Online / Chatham House, 10 St James's Square, London SW1Y 4LE
Think tank: Chatham House
This event hosted by UK think tank Chatham House discusses the implications of a ceasefire for Ukraine, Europe, Russia – and global security.
After more than four years, the war in Ukraine has entered a period of military stalemate on the ground and a vicious battle in the sky, with strikes hitting both Moscow and Kyiv. Numerous attempts to broach a ceasefire have failed. But talks of ending the war are growing.
If a ceasefire is finally agreed, it will create new questions: about Ukraine’s security, Russia’s ambitions, and Europe’s long-term stability – made more urgent by uncertainty over US commitment to European security.
This event marks the publication of our new paper entitled ‘How a Russia–Ukraine ceasefire could imperil Ukrainian and European security’.
- How might Russia and Ukraine approach ceasefire negotiations?
- What security conditions would a ceasefire create for Ukraine and Europe?
- What steps would be necessary to stabilize Ukraine after a ceasefire?
- How could Europe strengthen deterrence and security in the event of a pause in fighting?
- What might Putin’s next move be following a ceasefire?
- Would a ceasefire reduce the risk of future conflict or merely delay it?
