The preamble to the United Nations Charter pledges “to save succeeding generations from the scourge of war…” Can the UN remain relevant and impactful in world affairs? Behind headlines of global AI regulation and choosing the next Secretary General, key leaders are also charting the future of the UN Security Council, which – as the body tasked with preventing and stopping wars – could come closest to fulfilling the Charter’s defining mandate.
As
the UN General Assembly launches its 81st annual session, the agenda
includes deliberations on reforming the Security Council. Various proposals
would favor different approaches and competing interests, but real change won’t
depend on which plan is fairer or more efficient. The outcome will turn on what,
if anything, the Council’s five permanent members – the “P5” – choose to
accept.
Since the selection process for the UN’s next Secretary General will occupy most of the Security Council’s organizational attention, reforming the membership structure will not be less of a priority for the P5 than for the 10 non-permanent members that hold seats in overlapping two-year rotations. Streamlining and integrating the various proposals offers the best chance to advance the reform process.
CONTEXT FOR SECURITY COUNCIL REFORM
As the Great Powers to emerge victorious from World War II, the P5 – United States, Soviet Union, China, United Kingdom, and France – represented the main guarantors and enforcers of the UN’s nascent framework for collective security. In addition to designating them the only permanent members of the Council, the UN Charter accorded them exclusive veto rights, which incentivized their participation. By the 1960s, these five also controlled the world's nuclear weapons, and keeping them in the room talking probably helped keep the world from ending.
Fast-forward to 2026, and we have a few more nuclear powers, including India and Pakistan which each seek Council seats of their own along with a number of non-nuclear nations of international stature.
Several options have developed in recent years:
- “G4” – adds six permanent members (Brazil, Germany, India, Japan and two for Africa) and expanding the number of non-permanent members.
- African Group – increased representation from Africa, including two new permanent seats with veto power.
- France and Mexico – the P5 would agree to not use their veto in votes regarding war crimes and crimes against humanity.
- Uniting for Consensus (UfC) advanced by Pakistan, Argentina, Canada, Italy and Mexico – no expansion of permanent membership, but more non-permanent seats including a chance for reelection.
The G4 proposal includes a permanent seat for India, which – given its mutual animosity and hot conflict with neighboring Pakistan – is hardly a recipe for enhancing global security and stability. The same proposal includes Portuguese-speaking Brazil but not its comparably important — and Spanish-speaking — neighbor Argentina, as well as Germany, despite two other European countries already holding permanent seats.
REALISTIC PATHWAY TO 2030
Perfection is not an option here. No forum can satisfy the interest of every competing government, not to mention of 8 billion humans, while also maintaining global peace security – or even to come close. Of all the ways to improve the UN, especially as it faces open disdain and paralyzing budget cuts from the Trump administration, expanding an unruly body and introducing new combatants and rivalries seems like a recipe for failure and — if it succeeds — yet more contention, self-dealing, and deadlock; even so, it may work if the scales are at least somewhat balanced.
Since well-established regional groups coordinate the election of non-permanent members and organize regular consultations, the interests of specific member states are already reflected in the Council and eventually every nation gets to serve its own two-year term. All member states may attend Council meetings and, when relevant, participate in matters relating to their particular situations.
Nevertheless, given its sweeping mandate, there is wisdom in expanding the
Security Council to include influential and powerful member states even without
the perk of veto power. It is difficult to enforce and implement Council
decisions if modern-day movers and shakers were not even part of the
deliberations, notably Argentina, Brazil, India, Japan, Mexico, Nigeria, Pakistan,
Saudi Arabia, South Africa, South Korea and Türkiye.
The P5 are more likely to consider expansion proposals that preserve their exclusive veto power and limit additional members to heavy hitters, without turning the Council into another large and unwieldy UN commission. This should also be a priority for every government that values sustainable peace and security in the real world.
The likelihood of different coalitions consolidating behind a single, unified proposal is slim. Given that no changes can be made to the Security Council or the Charter without the assent of all P5, any Council reform probably won’t move so quickly. But if enough member states can be on record in support of a single pragmatic approach, then it will percolate and be available in 2030 – a target date for delivering on UN goals – when U.S. leadership and other wild cards could be ready to rebuild bigger and better.
