This publication considers the lessons to be gained for Britain, the British armed forces, and for NATO as a whole, from the Yugoslav wars of dissolution (1991-1999), with particular emphasis on the Kosovo crisis. The papers come from a diverse and high quality mixture of analysts, practitioners and policy-makers. The issues developed here represent a significant advance in the emerging debate on the lessons to be learnt from the Balkan experience, which will shape thinking on defence and international security far into the new millennium.
