Despite a changed international political context in the post-Cold War period, Western European small states remain firmly engaged in peace policy. One would be tempted to describe them as "natural born" peacemakers. This article shows a different approach to small states' peace policies. Using a typology from the literature on the role of norms and ideas, it argues that the type of peace engagement followed by small states has changed considerably during recent decades. More precisely, a shift has occurred in their peace policies from normative to cognitive ideas. This may be explained through their closer cooperation with international organisations (such as the EU), loss of significance of traditional role concepts such as neutrality, and the changed content of peace policies. Two consequences result from it: firstly, cognitive ideas are less linked to historically deep-rooted identities and therefore more prone to change; secondly, there fewer comparative advantages accrue to small states in promoting cognitive ideas. Thus, though small states remain very active peacebuilders, they have become less "natural" peacemakers than they used to be.
