Since its adoption in December 2015, United Nations Security Council Resolution 2250 on youth, peace, and security has been hailed as the first of its kind to recognize young people as meaningful drivers of change through its explicit encouragement of youth leadership at all levels of conflict prevention and peacebuilding. “It’s a testament to the fact that global youth today can have a real meaningful impact on the big issues of today, in the big arenas where discussions are happening,” said Andy Rabens, a special advisor on global youth issues for the U.S. Department of State, at the Wilson Center on October 6.
