The UK contribution to the war in Afghanistan took the lives of 457 UK armed forces personnel and injured thousands more, and cost more than £27 billion. The evacuation from Afghanistan in August 2021 resulted in 15,000 people being brought to the UK but left many behind. It is therefore of critical importance that the UK Government conduct an open, honest and detailed review of the UK’s involvement in the country. This review should include military operations and political decisions covering the full timeline of the UK’s involvement, from the terrorist attacks of September 11th 2001 and the invocation of Article 5 of the Washington Treaty, to the evacuation from Kabul in August 2021. This thinking would have been helpful to contribute to the update to the Integrated Review that is currently under way. (Paragraph 65) 24 Withdrawal from Afghanistan
