United Nations Security Council
On New Year's Day 1942, President Franklin Roosevelt and Prime Minister Winston Churchill signed a document known as the United Nations Declaration. Twenty-two other nations added their signatures the next day. This agreement laid the groundwork for an executive branch that would become the Security Council. The term Four Powers referred to the major Allied countries: the United States, the United Kingdom, the Soviet Union, and the Republic of China. These four nations formed the foundation of the new organization.
Delegations from these Big Four met at the Dumbarton Oaks Conference in Washington, D.C. during mid-1944. They negotiated the structure of the UN and the composition of its Security Council. France joined the group of permanent members alongside the original four powers. The US attempted to add Brazil as a sixth member but faced opposition from British and Soviet delegations. The most contentious issue was the veto right of permanent members. The Soviet delegation argued for absolute veto power while the British argued against it regarding disputes where they were parties.
At the Yalta Conference in February 1945, American, British, and Russian delegations agreed on the veto mechanism. Each of the Big Five could veto any action by the council except procedural resolutions. On the 25th of April 1945, the UN Conference on International Organization began in San Francisco with fifty governments attending. H.V. Evatt of the Australian delegation pushed to further restrict veto power. His proposal failed twenty votes to ten due to fears that rejecting strong veto would cause conference failure. The UN officially came into existence on the 24th of October 1945 upon ratification of the Charter. The Security Council held its first session on the 17th of January 1946 at Church House in London.
The Security Council remained largely paralyzed during the early decades of its existence because of Cold War tensions between the United States and the Soviet Union. It generally intervened only in conflicts unrelated to superpower interests. A notable exception occurred in 1950 when a resolution authorized a US-led coalition to repel North Korean invasion of South Korea. This vote passed despite the absence of the USSR from the meeting.
In 1956, the first UN peacekeeping force was established to end the Suez Crisis. However, the organization failed to intervene against the USSR's simultaneous invasion of Hungary following the Hungarian Revolution of 1956. Cold War divisions also paralyzed the Military Staff Committee created by Articles 45, 47 of the UN Charter. The committee existed on paper but abandoned most work by the mid-1950s.
During the 1960s, the UN deployed the largest military force of its early decades to restore order in the State of Katanga. This operation restored control to the Democratic Republic of the Congo by 1964. Yet the Security Council found itself bypassed in favor of direct negotiations between superpowers during larger conflicts like the Cuban Missile Crisis or the Vietnam War. Instead it focused on smaller conflicts without immediate Cold War connection. The United Nations Temporary Executive Authority operated in West New Guinea starting in 1962 while the Peacekeeping Force in Cyprus began operations in 1964.
After the collapse of the Soviet Union, UN peacekeeping duties expanded dramatically within a single decade. Between 1988 and 2000, adopted Security Council resolutions more than doubled while the peacekeeping budget increased over tenfold. The organization negotiated an end to the Salvadoran Civil War and launched successful missions in Namibia. It oversaw democratic elections in post-apartheid South Africa and Cambodia after Khmer Rouge rule ended.
In 1991, the Security Council demonstrated renewed vigor by condemning Iraqi invasion of Kuwait on the same day as the attack. A US-led coalition later repulsed Iraqi forces successfully. Undersecretary-General Brian Urquhart described these hopes as a false renaissance given subsequent troubled missions. The early 1990s brought simultaneous serious crises within nations including Haiti, Mozambique, and former Yugoslavia.
The mission to Bosnia faced worldwide ridicule for its indecisive approach during ethnic cleansing campaigns. In 1994, the United Nations Assistance Mission for Rwanda failed to intervene against genocide despite Security Council indecision. Late 1990s saw wider forms of international intervention including British Royal Marines supplementing Sierra Leone operations. NATO oversaw the 2001 invasion of Afghanistan under UN authorization. An internal review concluded in 2013 that the organization suffered systemic failure during final battles of Sri Lankan Civil War.
Five permanent members hold veto power over any substantive resolution: China, France, Russia, the United Kingdom, and the United States. These were the great powers victorious in World War II or their recognized successor states. A negative vote from any permanent member prevents adoption even if nine other votes support it. Abstention does not count as a veto in most cases but all five must vote yes for Charter amendments.
Since inception, 269 vetoes have been cast according to available records. The Soviet Union or Russia used this power 128 times while the United States employed it 89 times. Roughly two-thirds of combined Soviet and Russian vetoes occurred within the first ten years of existence. Between 1996 and 2012, the US vetoed thirteen resolutions while Russia vetoed seven and China vetoed five. France and the UK did not use the veto during that period.
An early veto by Soviet commissar Andrei Vishinsky blocked withdrawal of French forces from Syria and Lebanon in February 1946. This established precedent allowing permanent members to veto matters outside immediate war concerns. The Soviet Union went on to block admission of Austria, Cambodia, Ceylon, Finland, Ireland, Italy, Japan, Laos, Libya, Nepal, Portugal, South Vietnam, and Transjordan. The UK and France used the veto to avoid condemnation regarding actions in the 1956 Suez Crisis. From 1985 to 1990, the US vetoed twenty-seven resolutions primarily to block anti-Israel measures.
UN peacekeepers consist of military forces voluntarily provided by member states and funded independently of the main UN budget. These soldiers wear distinctive blue helmets earning them the nickname Blue Helmets. As of the 28th of February 2023, there were 86,903 uniformed and civilian personnel serving across twelve missions with contributions from 121 countries. The largest mission was MONUSCO in Democratic Republic of Congo including 20,688 uniformed personnel while the smallest included just forty-two observers monitoring Jammu Kashmir ceasefire.
The peacekeeping force received the Nobel Peace Prize in 1988 for its collective efforts. In fiscal year 2021-2022 expenditures reached $6.38 billion covering ten ongoing missions plus liquidation of Darfur operation. Top contributors included the US at 27.89 percent followed by China at 15.21 percent and Japan at 8.56 percent. Scientists cited Nepalese peacekeepers as likely source of 2010, 2013 Haiti cholera outbreak killing over eight thousand people following earthquake disaster.
Peacekeepers have faced criticism regarding child rape soliciting prostitutes or sexual abuse during various postings in Democratic Republic Congo Haiti Liberia Sudan South Sudan Burundi and Ivory Coast. The UN Truce Supervision Organization has been stationed in Middle East since 1948 making it longest-running active mission globally.
British historian Paul Kennedy concluded that glaring failures accompanied many achievements yet overshadowed them throughout first sixty years. He identified particular failures as lack of will to prevent ethnic massacres in Bosnia and Rwanda. Kennedy attributed these failures to insufficient reliable military resources available to the organization. Announcing new peacekeeping missions without ensuring sufficient armed forces usually proved recipe for humiliation and disaster.
A 2005 RAND Corporation study found UN successful in two out of three peacekeeping efforts compared to US nation-building operations. Eighty-eight percent of UN cases led to lasting peace according to findings. Scholar Sudhir Chella Rajan argued in 2006 that five permanent members created exclusive nuclear club addressing strategic interests rather than protecting resource-poor nations like Rwandans in 1994 while protecting oil-rich Kuwaitis in 1991.
The Security Council effectiveness remains questioned because most high-profile violations carry no consequences. Janjaweed militias committed violence against indigenous population killing thousands in Darfur crisis despite government elements allowing actions. Serbian troops committed genocide against Bosniaks in Srebrenica massacre although declared safe area protected by four hundred Dutch peacekeepers. Ayatollah Ali Khamenei criticized structure as illogical unjust completely undemocratic during August 2012 Non-Aligned Movement summit speech.
Proposals to reform Security Council began with conference writing UN Charter and continue today. British historian Paul Kennedy noted everyone agrees present structure flawed yet consensus on fixing it remains out of reach. Countries making strongest demands for permanent seats include Brazil Germany India and Japan known collectively as G4 nations. Japan and Germany were second third largest funders before China took over second place recently while Brazil India contribute large troop numbers to missions.
Italy leads movement called Uniting for Consensus opposing possible expansion of permanent seats. Core members include Canada South Korea Spain Indonesia Mexico Pakistan Turkey Argentina Colombia proposing new semi-permanent category elected extended duration instead. Former secretary-general Kofi Annan asked advisers to recommend reforms by end 2004 suggesting increase five permanent members including one African seat possibly Egypt Nigeria or South Africa plus Arab League representative. Currently proposal requires acceptance by two-thirds General Assembly reaching 128 votes minimum threshold.
In September 2017 US representatives Ami Bera Frank Pallone introduced resolution seeking support elevation India permanent membership. In 2025 at Rio de Janeiro BRICS Summit Brazilian President Luiz Inácio Lula da Silva Indian Prime Minister Narendra Modi emphasized shared ambition secure permanent UNSC seats better representing Global South economies excluded from decision-making.
