This chapter explores the Church of England’s response to the unexpected conflict with Argentina over the Falkland Islands (Malvinas). For a variety of reasons, the Archbishop of Canterbury responded slowly but came to support the government’s decision to send a military task force, arguing that this was broadly a just cause. As the references to ‘just war’ started to gain traction within church leadership circles, others within the church were becoming doubtful about any attempt to link war and justice, suggesting that sending a task force represented old fashioned gun-boat diplomacy that made conflict resolution more difficult, not less. Once the conflict was over, tensions over the war came to a head over a proposed service of thanksgiving, as the archbishop opted for a more irenic approach and some politicians sought more of a victory celebration.
