Since the early 1990s, the number of statebuilding projects has multiplied, often ending several years or even decades of violent conflict. The objectives of these missions have been formulated ad hoc, driven by the geopolitical contexts in which the mandates of statebuilding missions were established. However, after initial success in establishing a sense of physical security, the empirical evidence shows that most statebuilding efforts have failed, or achieved only moderate success. In some countries, violence has resumed after the initial end of hostilities. In others, the best results were authoritarian regimes based on fragile stalemates between warring parties. A review of the literature on statebuilding indicates a vast number of theories and approaches that often collide with each other, claim the exact opposite, and mount (contradictory) evidence in support of their mutually exclusive claims. Still they are united by their inquiry into the general structural and policy-making conditions that nurture or impede statebuilding processes. A problematic characteristic of the statebuilding literature is a lack of dialogue across the various disciplines. Many of the claims in the international relations literature on external statebuilding are a mirror image of the previous ones made on democratization. Another problem is the propensity to repeat the same mistakes of the previous generations.
