The United Nations Security Council ( UNSC) is one of the six principal organs of the United Nations (UN) and is charged with ensuring international peace and security, recommending the admission of new UN members to the General Assembly, and approving any changes to the UN Charter. Its powers as outlined in the United Nations Charter include establishing peacekeeping operations, enacting international sanctions, and authorizing military action. The UNSC is the only UN body with authority to issue resolutions that are binding on member states.
Like the UN as a whole, the Security Council was created after World War II to address the failings of the League of Nations in maintaining world peace. It held its first session on 17 January 1946 but was largely paralysed in the following decades by the Cold War between the United States and the Soviet Union (and their allies). Nevertheless, it authorized military interventions in the Korean War and the Congo Crisis and peacekeeping missions in Cyprus, West New Guinea, and the Sinai Peninsula. With the collapse of the Soviet Union, UN peacekeeping efforts increased dramatically in scale, with the Security Council authorizing major military and peacekeeping missions in Gulf War, Namibia, Cambodia, Bosnia and Herzegovina, Rwanda, Somalia, Sudan, and the Kivu conflict.
The Security Council consists of fifteen members, of which five are permanent: China, France, Russia, the United Kingdom, and the United States. These were the that were the victors of World War II (or their recognized successor states). Permanent members can veto any substantive Security Council resolution, including those on the admission of new member states to the United Nations or nominees for the Office of Secretary-General. This veto right does not carry over into General Assembly matters or votes, which are non-binding. The other ten members are elected on a regional basis for a term of two years. The body's presidency rotates monthly amongst its members.
Resolutions of the Security Council are typically enforced by UN peacekeepers, which consist of military forces voluntarily provided by member states and funded independently of the main UN budget. , there have been 12 peacekeeping missions with over 87,000 personnel from 121 countries, with a total annual budget of approximately $6.3 billion.
On New Year's Day 1942, President Roosevelt, Prime Minister Churchill, Maxim Litvinov of the USSR, and T. V. Soong of the Republic of China, signed a short document, based on the Atlantic Charter and the London Declaration, which later came to be known as the United Nations Declaration. The next day the representatives of 22 other nations added their signatures. The term "United Nations" was first officially used when 26 governments had signed the Declaration. By 1 March 1945, 21 additional states had signed. The term "Four Policemen" was coined to refer to the four major Allied countries: the United States, the United Kingdom, the Soviet Union and the Republic of China. and became the foundation of an executive branch of the United Nations, the Security Council.
Following the 1943 Moscow Conference and Tehran Conference, in mid-1944, the delegations from the Allied "Four Policemen", the Soviet Union, the UK, the US and the Republic of China, met for the Dumbarton Oaks Conference in Washington, D.C. to negotiate the UN's structure, and the composition of the UN Security Council quickly became the dominant issue. France, the Republic of China, the Soviet Union, the UK and US were selected as permanent members of the Security Council; the US attempted to add Brazil as a sixth member but was opposed by the heads of the Soviet and British delegations. The most contentious issue at Dumbarton and in successive talks proved to be the veto rights of permanent members. The Soviet delegation argued that each nation should have an absolute veto that could block matters from even being discussed, whilst the British argued that nations should not be able to veto resolutions on disputes to which they were a party. At the Yalta Conference of February 1945, the American, British and Russian delegations agreed that each of the "Big Five" could veto any action by the council, but not procedural resolutions, meaning that the permanent members could not prevent debate on a resolution.
On 25 April 1945, the UN Conference on International Organization began in San Francisco, attended by fifty governments and a number of non-governmental organizations involved in drafting the United Nations Charter. At the conference, H. V. Evatt of the Australian delegation pushed to further restrict the veto power of Security Council permanent members. Due to the fear that rejecting the strong veto would cause the conference's failure, his proposal was defeated twenty votes to ten.
The UN officially came into existence on 24 October 1945 upon ratification of the Charter by the five then-permanent members of the Security Council and by a majority of the other 46 signatories. On 17 January 1946, the Security Council met for the first time at Church House, Westminster, in London, United Kingdom. Subsequently, during the 1946–1951 period it conducted sessions at the United Nation's interim headquarters in Lake Success, New York, which were televised live on CBS by the journalist Edmund Chester in 1949.
In 1960, the UN deployed the United Nations Operation in the Congo (UNOC), the largest military force of its early decades, to restore order to the breakaway State of Katanga, restoring it to the control of the Democratic Republic of the Congo by 1964. However, the Security Council found itself bypassed in favour of direct negotiations between the superpowers in some of the decade's larger conflicts, such as the Cuban Missile Crisis or the Vietnam War. Focusing instead on smaller conflicts without an immediate Cold War connection, the Security Council deployed the United Nations Temporary Executive Authority in West New Guinea in 1962 and the United Nations Peacekeeping Force in Cyprus in 1964, the latter of which would become one of the UN's longest-running peacekeeping missions.
On 25 October 1971, over US opposition, but with the support of many Third World nations, along with the Socialist People's Republic of Albania, the mainland, communist People's Republic of China replaced Republic of China with a seat on the Security Council; the vote was widely seen as a sign of waning US influence in the organization. With an increasing Third World presence and the failure of UN mediation in conflicts in the Six-Day War, Vietnam War and Kashmir, the UN increasingly shifted its attention to its ostensibly secondary goals of economic development and cultural exchange. By the 1970s, the UN budget for social and economic development was far greater than its budget for peacekeeping.
Though the UN Charter had been written primarily to prevent aggression by one nation against another, in the early 1990s, the UN faced a number of simultaneous, serious crises within nations such as Haiti, Mozambique and the former Yugoslavia. The UN mission to Bosnia faced "worldwide ridicule" for its indecisive and confused mission in the face of ethnic cleansing.For quotation "worldwide ridicule", see ; for description of UN missions in Bosnia, see . In 1994, the United Nations Assistance Mission for Rwanda failed to intervene in the Rwandan genocide in the face of Security Council indecision.
In the late 1990s, UN-authorized international interventions took a wider variety of forms. The UN mission in the 1991–2002 Sierra Leone Civil War was supplemented by British Royal Marines and the UN-authorized 2001 invasion of Afghanistan was overseen by NATO. In 2003, the US Iraq War despite failing to pass a UN Security Council resolution for authorization, prompting a new round of questioning of the organization's effectiveness. In the same decade, the Security Council intervened with peacekeepers in crises including the War in Darfur in Sudan and the Kivu conflict in the Democratic Republic of Congo. In 2013, an internal review of UN actions in the final battles of the Sri Lankan Civil War in 2009 concluded that the organization had suffered "systemic failure".
In November/December 2014, Egypt presented a motion proposing an expansion of the NPT (non-Proliferation Treaty), to include Israel and Iran; this proposal was due to increasing hostilities and destruction in the Middle-East connected to the Syrian Conflict as well as others. All members of the Security Council are signatory to the NPT, and all permanent members are nuclear weapons states.
Under Chapter VI of the Charter, "Pacific Settlement of Disputes", the Security Council "may investigate any dispute, or any situation which might lead to international friction or give rise to a dispute". The Council may "recommend appropriate procedures or methods of adjustment" if it determines that the situation might endanger international peace and security. These recommendations are generally considered to not be binding, as they lack an enforcement mechanism.See ; ; ; ; . For lack of enforcement mechanism, see . A minority of scholars, such as Stephen Zunes, have argued that resolutions made under Chapter VI are "still directives by the Security Council and differ only in that they do not have the same stringent enforcement options, such as the use of military force".
Under Chapter VII, the council has broader power to decide what measures are to be taken in situations involving "threats to the peace, breaches of the peace, or acts of aggression." In such situations, the council is not limited to recommendations but may take action, including the use of armed force "to maintain or restore international peace and security." This was the legal basis for UN armed action in Korea in 1950 during the Korean War and the use of coalition forces in Iraq and Kuwait in 1991 and Libya in 2011. Decisions taken under Chapter VII, such as economic sanctions, are binding on UN members; the Security Council is the only UN body with authority to issue binding resolutions.
The Rome Statute of the International Criminal Court recognizes that the Security Council has authority to refer cases to the Court in which the Court could not otherwise exercise jurisdiction. Article 13 of the Rome Statute. United Nations. Retrieved 26 November 2013. The Council exercised this power for the first time in March 2005, when it referred to the Court "the situation prevailing in Darfur since 1 July 2002"; since Sudan is not a party to the Rome Statute, the Court could not otherwise have exercised jurisdiction. The Security Council made its second such referral in February 2011 when it asked the ICC to investigate the Libyan government's violent response to the Libyan Civil War.
Security Council Resolution 1674, adopted on 28 April 2006, "reaffirms the provisions of paragraphs 138 and 139 of the 2005 World Summit Outcome Document regarding the responsibility to protect populations from genocide, war crimes, ethnic cleansing and crimes against humanity". The Security Council reaffirmed this responsibility to protect in Resolution 1706 on 31 August of that year. These resolutions commit the Security Council to protect civilians in an armed conflict, including taking action against genocide, war crimes, ethnic cleansing and crimes against humanity.
At the UN's founding in 1945, the five permanent members of the Security Council were the Republic of China, France (represented by the Provisional Government of the French Republic), the Soviet Union, the United Kingdom, and the United States. There have been two major seat changes since then. China's seat was originally held by Chiang Kai-shek's Nationalist Government, the Republic of China. However, the Nationalists were forced to retreat to the island of Taiwan in 1949, during the Chinese Civil War. The Chinese Communist Party assumed control of mainland China, thenceforth known as the People's Republic of China. In 1971, General Assembly Resolution 2758 recognized the People's Republic as the One-China policy in the UN and gave it the seat on the Security Council that had been held by the Republic of China, which was expelled from the UN altogether with no opportunity for membership as a separate nation. After the dissolution of the Soviet Union in 1991, the Russian Federation was recognized as the legal successor state of the Soviet Union and maintained the latter's position on the Security Council.
The five permanent members of the Security Council were the victorious powers in World War II and have maintained the world's most powerful military forces ever since. They annually topped the list of countries with the highest military expenditures. In 2013, they spent over US$1 trillion combined on defence, accounting for over 55% of global military expenditures (the US alone accounting for over 35%). They are also amongst the world's largest arms exporters and are the only nations officially recognized as "nuclear-weapon states" under the Nuclear Non-Proliferation Treaty (NPT), though there are other states known or believed to be in possession of nuclear weapons.
The block of Western democratic and generally aligned permanent members (France, the UK and the US) is styled as the "P3".
In the negotiations leading up to the creation of the UN, the veto power was opposed by many small countries and was in fact forced on them by the veto nations—the United States, the United Kingdom, China, France, and the Soviet Union—by threatening that the UN would otherwise not be founded. Francis O. Wilcox, an adviser to the US delegation to the 1945 conference, described the situation:
, 269 vetoes had been cast since the Security Council's inception. In this period, China used the veto 9 times, France 18, the Soviet Union or Russia 128, the United Kingdom 32, and the United States 89. Roughly two-thirds of Soviet and Russian combined vetoes were in the first ten years of the Security Council's existence. Between 1996 and 2012,
the United States vetoed 13 resolutions, Russia 7, and China 5, whilst France and the United Kingdom did not use the veto.
An early veto by Soviet Commissar Andrei Vishinsky blocked a resolution on the withdrawal of French forces from Syria and Lebanon which were under French mandate in February 1946; this veto established the precedent that permanent members could use the veto on matters outside of immediate concerns of war and peace. The Soviet Union went on to veto matters including the admission of Austria, Cambodia, Ceylon, Finland, Ireland, Italy, Japan, Laos, Libya, Nepal, Portugal, South Vietnam and Transjordan as UN member states, delaying their joining by several years. The United Kingdom and France used the veto to avoid Security Council condemnation of their actions in the 1956 Suez Crisis. The first veto by the United States came in 1970, blocking General Assembly action in Southern Rhodesia. From 1985 to 1990, the US vetoed 27 resolutions, primarily to block resolutions perceived as anti-Israel but also to protect its interests in Panama and Korea. The Soviet Union, the United States and China have all vetoed candidates for Secretary-General, with the US using the veto to block the re-election of Boutros Boutros-Ghali in 1996.
These ten non-permanent members are elected by the United Nations General Assembly for two-year terms starting on 1 January, with five replaced each year. To be approved, a candidate must receive at least two-thirds of all votes cast for that seat, which can result in deadlock if there are two roughly evenly matched candidates. In 1979, a standoff between Cuba and Colombia only ended after three months and a record 154 rounds of voting; both eventually withdrew in favour of Mexico as a compromise candidate. A retiring member is not eligible for immediate re-election.
The African Group is represented by three members; the Latin America and the Caribbean, Asia-Pacific, and Western European and Others groups by two apiece; and the Eastern European Group by one. Traditionally, one of the seats assigned to either the Asia-Pacific Group or the African Group is filled by a nation from the Arab world, alternating between the groups. Currently, elections for terms beginning in even-numbered years select two African members, and one each within Eastern Europe, Asia-Pacific, and Latin America and the Caribbean; the traditional "Arab seat" is elected for this term. Terms beginning in odd-numbered years consist of two Western European and Other members, and one each from Asia-Pacific, Africa, and Latin America and the Caribbean.
During the 2016 United Nations Security Council election, neither Italy nor the Netherlands met the required two-thirds majority for election. They subsequently agreed to split the term of the Western European and Others Group. It was the first time in over five decades that two members agreed to do so. Usually, intractable deadlocks are resolved by the candidate countries withdrawing in favour of a third member state.
The current elected members, with the regions they were elected to represent, are as follows:
