Since Donald Trump’s return to the US presidency, the UN system has come under unprecedented pressure. UN Secretary-General António Guterres and the UN Secretariat were already struggling with a protracted liquidity crisis (caused by recurrent delayed or incomplete payment of assessed contributions from major contributors such as the United States and China), looming reductions in major donors’ voluntary contributions and rising geopolitical tensions among UN member states (Camelli & Patz, 2026; Haug, 2024). But the Trump administration’s disdain for multilateralism in general, and the UN in particular, poses an even more fundamental and pressing challenge to the UN, both financially and (geo)politically. Since the establishment of the UN in 1945, the United States has played a key role as the host for the UN headquarters in New York and the largest contributor to UN budgets. Although relations between the UN and the US government have long been complex – with influential anti-UN voices persistently present in US domestic politics (Browne & Nakamura, 2009; Mingst, 2003) – it had never reached a point at which broader US support for the organisation appeared to be under threat. This has changed, as exemplified by the formal or de facto withdrawal of the United States from many parts of the UN system, including withdrawal from the World Health Organization (WHO) and the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 2025, as well as disengaging from 31 other UN entities in 2026 (The White House, 2026). With the faltering hegemonic position of the United States, a general turn to overt geopolitics (Haug, 2026) and “my-country-first” policies, as well as long-standing criticism about the organisation’s inefficiencies, duplication and fragmentation – driven by donors’ chronic uncoordinated funding behaviour – the UN’s position as the centre of an imperfectly functioning multilateral system is at stake. Other major powers and blocs – from China and the BRICS grouping to the EU and a diverse group of medium-sized states from across the globe – have been unable to put forward a joint response to the fickle and often adversarial posture of the United States. Many have instead exhibited more transactional and self-focused behaviour, such as advocating for UN staff relocations to their own countries. So far, there is no shared vision of what the future of multilateral cooperation through the UN system – including its development, humanitarian and global regulatory agencies – ought to look like. Against this backdrop, we first outline why recent reform attempts under the so-called UN80 Initiative – triggered primarily by the shift in US policy towards multilateral organisations – have missed several opportunities to strategically reform and strengthen the UN system. We then argue that UN multilateralism is still needed – maybe more than ever before. Finally, we turn to recommendations on what stakeholders should do in order to make the UN fit for purpose in an increasingly challenging global environment.
