World Humanitarian Day is an international celebration that commemorates both the accomplishments and sacrifices of humanitarian aid personnel who work in difficult and dangerous environments. Without their dedication to humanity, the delivery of life-saving aid and technical support to millions across the globe would not be possible. The discussion focused on the future of humanitarian assistance, evolving challenges in the aid community, and U.S. leadership within this sector moving forward.
