In the world of Walls, nation states prioritise narrow domestic interests, retreating from broad international collaboration and increasing polarisation. They invest heavily in security and militarisation, addressing climate change and health crises within their borders rather than seeking global solutions. As resources and political support for multilateralism dwindle, states mostly use the system for power-based negotiations or unilateral actions. Military tensions dominate global headlines and national security strategies, while resource extraction from resource rich countries intensifies. Escalating wars lead to a multipolar and fragmented world, where strong authoritarian states control spheres of influence through military, economic and digital sabotage or warfare, and seek to deter others from interfering. Local civil society groups are subject to strict regulations, struggling to survive in this heavily securitised environment.
