The nature of conflict and violence has transformed substantially since the UN was founded 75 years ago. Conflicts now tend to be less deadly and often waged between domestic groups rather than states. Homicides are becoming more frequent in some parts of the world, while gender-based attacks are increasing globally. The long-term impact on development of inter-personal violence, including violence against children, is also more widely recognized. Separately, technological advances have raised concerns about lethal autonomous weapons and cyberattacks, the weaponization of bots and drones, and the livestreaming of extremist attacks. There has also been a rise in criminal activity involving data hacks and ransomware, for example. Meanwhile, international cooperation is under strain, diminishing global potential for the prevention and resolution of conflict and violence in all forms.
