The integration of political, military, and humanitarian action in responding to complex emergencies offers a compelling promise of resolving long-term problems and thereby providing peace and stability to an entire population. Significant changes are needed, however, to realize this promise fully. The most critical improvements relate to strengthening the humanitarian leadership within the UN system and so refocusing the collective effort on the protection of vulnerable civilians. A movement of independent, complementary agencies working together to realize protection will strengthen the humanitarian component of integrated missions and make a difference in people's lives.
