<h1>World leaders meet at UN amid wars, funding cuts and polarization to debate Gaza, Ukraine, climate, AI, development</h1> World leaders convene at the UN amid concurrent wars, geopolitical polarization and technological and climate risks, while the UN faces deep funding and staffing cuts that its leadership says require urgent reform and cooperation. Key agenda items include Gaza, the Israeli-Palestinian question and a proposed two-state solution, the war in Ukraine, global security hotspots, climate action, AI governance and financing for 2030 development goals. Tensions center on differing national stances, visa denials and contested reports of atrocities, and major powers' policies will shape outcomes; observers warn progress is uncertain given polarisation and reduced UN resources.
