Unbeknownst to me, the United States Congress has been funding the US Institute of Peace since 1984. Recently they updated their website and have made it a lot better, they’ve added podcasting, and archived recordings. The USIP also offers online training. You should check out their impressive Library!
“Its goals are to help prevent and resolve violent international conflicts, promote post-conflict stability and democratic transformations, and increase peacebuilding capacity, tools, and intellectual capital worldwide. The Institute does this by empowering others with knowledge, skills, and resources, as well as by its direct involvement in peacebuilding efforts around the globe. “
