When world leaders converge on New York City this week for the annual gathering of the United Nations General Assembly, the organization will be observing its 80th anniversary. But the mood is far from celebratory, as wars rage around the world, a budget crisis looms and questions abound about whether the U.N. is even relevant anymore. Year after year, U.N. officials and world leaders use the annual gathering to put forth lofty ideas and offer elaborate road maps for change. And the world is still nowhere near achieving its goals on development or a solution for climate change. Even the United Nations’ global humanitarian aid work — one of the few areas where the organization has continued to excel and lead the world — is now threatened by budget cuts, donor apathy and staff reductions.
