International development is a more effective method of preventing failed states.  The current US approach to international development, in which aid, loans or market access are conditional upon good governance, should be maintained and even extended more widely. Such conditions provide incentives for developing countries to put constructive policies in place and reward those who fight corruption. As past failures show all too clearly, there is no point throwing money at chaotic, lawless and corrupt regimes - it will never reach the people anyway. In any case, humanitarian relief is not conditional and the USA continues to respond with compassion to emergencies anywhere in the world. It should also be noted that special measures to support states identified as at risk of failure could in themselves be harmful. Discussion of intervention will scare off investors and help to bring about economic collapse - becoming self-fulfilling prophecies.
