Popperian Peacebuilding, Policing and the Liberal Peace

In light of the quarrelling between advocates and critics of the liberal peacebuilding agenda, this article calls for the adoption of a 'Popperian' approach. This approach would be one that seeks to identify and address the greatest evils to fundamental liberal principles rather than undertaking swift and sweeping liberalization projects. Tolerance is therefore advocated in all matters that fall outside of this remit in order to temper the current zeal displayed by the liberal peacebuilding agenda. The article then considers how Popperian approaches and the ideal of tolerance were lacking in the case of peacebuilding in the security sector in Timor-Leste. In failing to ensure a clear separation of police and military forces that are apolitical, loyal to the state and professional in serving the liberal democratic polity, for example, international actors inadvertently allowed a 'great evil' to emerge. Rather than being distracted and diluted by a sweeping range of goals, international actors should seek to work from these fundamental concepts and be prepared to negotiate on less urgent matters.
