The Fragile States Index presents a diagnosis of the problem, the first step in devising strategies for strengthening weak and failing states. The more reliably policymakers can anticipate, monitor, and measure problems, the more they can act to prevent violent breakdowns, protect civilians caught in the crossfire, and promote recovery. At the same time, policymakers must focus on building the institutional capacity of weak states, particularly the “core five” institutions: military, police, civil service, the system of justice, and leadership. Policies should be tailored to the needs of each state, monitored and evaluated intensively, and changed, as necessary, if recovery is not occurring as intended. Continuous monitoring of the measures, using the same assessment methodology, can inform decision making on strategies and programs.
