Challenges to Multilateral Cooperation

The institutional architecture built after 1945 has faced recurring structural strain from the veto power vested in the UN Security Council's five permanent members, a mechanism that has repeatedly blocked collective action on major crises: Russia has vetoed numerous resolutions on Syria since the country's civil war began in 2011 and on its own 2022 invasion of Ukraine, while the United States has used its veto to shield Israel from Council censure over the conduct of the Gaza war that began in October 2023, most notably vetoing a December 2023 ceasefire resolution. Reform proposals have circulated for decades without success: the "G4" grouping of Germany, Japan, India, and Brazil has long lobbied for permanent Council seats reflecting contemporary economic and demographic weight rather than the victors of the Second World War, while the "Uniting for Consensus" group, led by Italy, Pakistan, Mexico, and South Korea, opposes expanding the number of veto-wielding permanent members; no reform has secured the two-thirds General Assembly majority and ratification by all five existing permanent members that Charter amendment requires.
