You mentioned most of what I was going to, so I'll also add Somalian Civil War, Sierra Leone Civil War, Rwandan Genocide, First Congo War, the start of the Second Congo War, the Dot Com Bubble, repeal of Glass Stegal that led to the 2008 Recession, the Blood-Crips feud, Columbine, University of Iowa Shooting, Westside Middle School Shooting, Thurston High School Shooting (AKA the Kimp Kinkel Shooting), Lindhurst High Shooting, Pearl High Shooting, Heath High Shooting, Frontier Middle School Shooting, and the BTK Killer was still active until at least 1991 (possibly longer as he wasn't caught until 2005). Also a few dictators acting as US puppets. And all the awful shit going on in the wake of the USSR's collapse, including Russia and Ukraine.
