This article considers Estonia’s contribution, since May 2015, of an infantry company to the Finnish contingent of the Finnish/Irish battalion of the United Nations Interim Force in Lebanon. It is intended to provide a case study of a small European state’s involvement in UN peacekeeping in the ‘post-Afghanistan’ security environment. Drawing on interviews with Estonian officials and peacekeepers, it sets out the rationale for Estonia’s contribution and explores the degree to which participation has met the expectations of the Estonian defence leadership. It concludes that participation in UNIFIL has largely been a valuable policy, both politically and for the defence forces.
