Two decades ago saw the start of Europe's bloodiest military conflict since the Second World War. The Bosnian War and the break-up of the former Yugoslavia reignited ethnic conflicts between Muslims and Serbs. Over four years, around 100-thousand people were killed, and more than 4 million displaced. The war eventually saw NATO's first-ever peace mission in its history - setting a template for incursions into foreign troublespots. Anti-NATO activist Rick Rozoff believes the Alliance's current interventions make it hard for nations to resolve their conflict themselves.
