Nuclear disarmament around the world

The campaign for nuclear disarmament is not just an organisation, but a global movement with campaigners found across the world working towards a nuclear-free world. Those campaigners and activists made a huge advance in 2017 when The Treaty on the Prohibition of Nuclear Weapons (TPNW) was adopted by the United Nations General Assembly. It is the first legally binding agreement banning nuclear weapons, and will enter into force once 50 countries have ratified it.

Previous treaties, such as the 1968 Treaty on the Non-Proliferation of Nuclear Weapons (NPT), have helped to limit the number of states with nuclear weapons. No treaty, however, has resulted in disarmament. The TPNW is designed to go further than previous treaties, nations which are party to the treaty cannot develop, test, produce, stockpile, station, transfer, use or threaten to use nuclear weapons. In short, they cannot have anything to do with them. For nuclear armed states, joining the treaty means they must work to get rid of their nuclear weapons for good, and in a certain amount of time.

The treaty will only come into force once it has been ratified by 50 states, which is different to simply signing the treaty. Ratification usually requires a senior government official or head of state approving the treaty and making sure it does not contradict any existing laws that country has. So far, the treaty has 84 signatories and 50 state parties, a country becomes a ‘state party’ to a treaty once it has ratified to that particular treaty. Below, you can find out some information on each of the countries which have ratified the TPNW.

The treaty was ratified by the 50th state party, Honduras, on the 24th October 2020, and will enter into force on 22nd January 2021.

Antigua and Barbuda  Flag: Antigua & Barbuda on Twitter

Antigua and Barbuda is an island state in the West Indies made up of two separate islands, Antigua and Barbuda which are 39 miles apart and found between the Caribbean and the Atlantic. Antigua and Barbuda participated in the negotiation of the treaty at the United Nations in New York in 2017 and ratified it in September 2018.

Austria  Flag: Austria on Twitter

Austria is a landlocked country in central Europe. Austria was one of the main drivers behind the treaty and since the end of the Cold War it has been heavily involved in peace and disarmament through its promotion and signing of the Anti-Personnel Mine Ban Convention (Ottawa Treaty) in 1997 and the Convention on Cluster Munitions signed in Oslo in 2008.

Bangladesh  Flag: Bangladesh on Twitter

Bangladesh sends more of its troops than any other country in the world to the United Nations peace-keeping forces. It is a very densely populated country located to the East of India – both India and nearby Pakistan have between 100 and 200 nuclear weapons each. Its landscape features several huge rivers and therefore its land is very fertile too.

Belize  Flag: Belize on Twitter

Belize is a Caribbean country located in Central America, it was colonised by the British Empire and still has Queen Elizabeth II as its head of state. Due to its position between North and South America, Belize has a uniquely diverse eco-system with a wide variety of land based and marine species found in the country.

Bolivia  Flag: Bolivia on Twitter

Bolivia is a land-locked country in the Western part of South America. In recent years Bolivia has taken a number of steps to promote nuclear disarmament through endorsing the ‘humanitarian pledge’ in 2015 to cooperate ‘in efforts to stigmatise, prohibit, and eliminate nuclear weapons’, this helped to build momentum for the negotiations which led to the signing of the TPNW.

Botswana  Flag: Botswana on Twitter

Botswana is a land-locked African country in the southern part of the continent. It became the most recent state to ratify the TPNW on 15 July 2020, an important day that marked 75 years since the ‘Trinity test’, which was the first atomic bomb test explosion. It is Africa’s oldest democracy, running democratic elections since 1988 and is also one of the most sparsely populated countries in the world.

Cook Islands  Flag: Cook Islands on Twitter

The Cook Islands are a collection of 15 islands in the southern part of the Pacific Ocean. The islands govern themselves but are in association with New Zealand who have typically made decisions on foreign affairs on their behalf. However, more recently the Cook Islands have an increasingly independent foreign policy and the ratification of the TPNW was completed by the ministry of foreign affairs of the Cook Islands. Cook islanders often take a strongly anti-nuclear stance as many of them can remember seeing nuclear tests happening from their homes. The Cook Islands are a signatory to the Rarotonga treaty which established the South Pacific as a nuclear free zone.

Costa Rica  Flag: Costa Rica on Twitter

Cota Rica is a country in the heart of Central America. The country has a long history of pacifism, having abolished its army in 1948 and dedicating that money to health care and education. As a result, Costa Rica often ranks favourably on the Human Development Index (HDI) which ranks countries based on life expectancy, education and income per head.

Cuba  Flag: Cuba on Twitter

Cuba is a country made up of the island of Cuba and Isla de la Juventud in the Caribbean. Cuba’s anti-nuclear stance is partly owed to its involvement in the 1962 Cuban missile crisis where a full-scale nuclear war nearly broke out between the United States and the Soviet Union. In response to an attempt to overthrow the Cuban government by the United States, known as the Bay of Pigs invasion, the Soviet Union, with the permission of Cuban leader Fidel Castro, placed nuclear missile launch facilities on the island of Cuba, 140km from Florida. The US blocked the delivery of the missiles to the island resulting in a confrontation which put both states, and the world, at risk of nuclear war. This was resolved after then leader of the Soviet Union, Nikita Kruschev, sent a message to then US President John F Kennedy offering to remove the missiles if the US promised not to overthrow the Cuban government and to remove its missiles from Turkey. Had it been rejected, a US invasion of Cuba, followed by a nuclear retaliation from the Soviet Union would have been likely.

Dominica  Flag: Dominica on Twitter

Dominica is an island in the Caribbean. It is unique for being a relatively ‘young’ island, in geological terms, and one which is still being shaped by geo-thermal activity. It is home to the world’s second largest hot spring known as the ‘boiling lake’ filled with bubbling grey-blue water and covered by a thick cloud of vapour.

Ecuador  Flag: Ecuador on Twitter

Fiji  Flag: Fiji on Twitter

Fiji is an island country in the southern part of the Pacific Ocean made up of around 330 islands. Fiji’s ratification of the TPNW in July 2020 came after over half a century of anti-nuclear activism. Anti-Nuclear activists in Fiji have been resisting what Father Walter Lini, later Vanuatu’s first prime minister, described as ‘nuclearism’ (a combination of ‘nuclear’ and ‘colonialism’), whereby the United States, France and Britain carried out permanently damaging nuclear weapons testing on the Pacific island territories until as recently at 1996.

The Gambia  Flag: Gambia on Twitter

The Gambia is a country in West Africa and is the smallest country on the African content. The Gambia was the first African country to ratify the TPNW and its army, the Gambia Armed Forces have been active in UN and African Union peacekeeping missions since the 1980s.

The Holy See is the term for the Bishop of Rome’s central offices that serve the Roman Catholic church. The Holy See isn’t technically a country but is located in the Vatican City – both of which are led by Pope Frances. The Pope made a historic visit to the cities of Hiroshima and Nagasaki, which had nuclear weapons dropped on them by the United States at the end of the Second World War. On the visit in 2019, the Pope condemned the use and possession of nuclear weapons as ‘immoral’ and urged support for ‘the principal international legal instruments of nuclear disarmament and non-proliferation, including the Treaty on the Prohibition of Nuclear Weapons’.

Honduras  Flag: Honduras on Twitter

The Republic of Ireland  Flag: Ireland on Twitter

The Republic of Ireland covers 80% of the island of Ireland and shares a border with the United Kingdom, which has 200 nuclear weapons. Ireland is also known as the Emerald Isle because of its famously lush, green countryside. Internationally, Ireland has been an important state for disarmament. The ‘Irish resolutions’, put forward at the United Nations (UN) in 1958, lead to the adoption of the Non-Proliferation Treaty, which stops countries gaining more nuclear weapons. More recently, Ireland was one the countries that first proposed the Treaty on the Prohibition of Nuclear Weapons (TPNW). They ratified the TPNW on Hiroshima Day, 6th August 2020, saying: ‘There can be no right hands for the wrong weapons’.

Jamaica  Flag: Jamaica on Twitter

Jamaica was the penultimate (second to last) country to ratify the treaty before it reached the important 50 state parties necessary to turn the agreement into international law. Its flag is the only flag to be made up of yellow, green and black – colours which are associated with Jamaican culture around the world due to a large population of Jamaicans living abroad e.g. the ‘Windrush’ generation and their descendants in the UK.

Kazakhstan  Flag: Kazakhstan on Twitter

Kazakhstan is a country which stretches from Eastern Europe to Central Asia and is the largest landlocked country in the world. The date that Kazakhstan ratified the treaty, August 29th, 2019, coincided with the UN International Day against Nuclear tests, and marks 70 years since the first Soviet nuclear test was conducted at the Semipalatinsk test site in Kazakhstan. Between 1949 and 1989, an estimated 456 nuclear tests were carried out in Kazakhstan. These have devastating long-term consequences for human health and the environment. Upon the break-up of the Soviet Union in 1991, Kazakhstan inherited approximately 1,400 Soviet nuclear warheads, which it gave up in the interests of disarmament.

Kiribati  Flag: Kiribati on Twitter

Kiribati is a country in the middle of the Pacific Ocean. Kiribati’s opposition to nuclear weapons can be traced back to its use as a nuclear testing site at the beginning of the cold war. Between 1957 and 1962, the United Kingdom and the United States tested 33 nuclear weapons at Malden and Kiritimati islands in Kiribati. This severely disrupted the lives of those living on the island and has resulted in devastating long term environmental and health impacts.

Laos  Flag: Laos on Twitter

Laos is a South-East Asian country and the only landlocked country in the region. It is a very sparsely populated country, with a population of around 7m people in a country which is 236,800 sq km large, meaning there are around 30 people per square kilometre.

It is the 10th smallest country in the world and is a member of the European Union (EU). Its location in the Mediterranean has long been seen as militarily significant, and this in part lead to its colonisation by the British Empire from 1813-1964.

Mexico  Flag: Mexico on Twitter

Mexico is a North American country bordering the United States. Mexico is distinct in that it is one of the few countries which has the technical capability to produce nuclear weapons but in 1968 it abandoned their development and pledged to use the technology for peaceful purposes. Since then Mexico has been a driving force in the campaign for global disarmament, making up one of a small group of states that played a leading role in bringing the TPNW negotiations about and ensuring their ultimate success.

Namibia  Flag: Namibia on Twitter

Nauru  Flag: Nauru on Twitter

Nauru is an island country of just 8 square miles in the Pacific Ocean. With a population of only 10,000 it may seem small, but given that it was colonised by Japan in WW2, and later was under ‘trusteeship’ by the United Nations, Nauru has been very active in international affairs since its independence in 1968. It has provided the world with high-quality phosphate, but has become involved in Australia’s hard-line immigration policies and serves as a site for so-called ‘offshore processing’ of asylum seekers, refugees and migrants.

New Zealand  Flag: New Zealand on Twitter

New Zealand is an island country in the southwestern Pacific Ocean. It has long been one of the strongest advocates for a nuclear free world in the United Nations which it describes as the country’s ‘signature foreign policy’. This can be traced back to the decision of, then Labour prime minister, Norman Kirk in 1973, to send a warship with a minister on board to protest against French nuclear testing at Mururoa atoll. New Zealand’s reputation as an anti-nuclear state was further enhanced when 1984, Prime Minister David Lange banned nuclear-powered or nuclear-armed ships from using New Zealand ports or entering New Zealand waters. Anti-Nuclear policy is a key part of New Zealand’s political identity.

Nicaragua  Flag: Nicaragua on Twitter

Nicaragua is a Central American country and the largest country within the Central American region. Nicaragua is one of only of three countries, alongside the United States and Syria, not to sign up to the Paris climate accords. Unlike the other two states however, this is due to its criticism of the agreement for not going far enough, arguing that much more ambitious targets are required.

Nigeria  Flag: Nigeria on Twitter

Nigeria is a large country in West Africa with a large population. Its people are diverse and together speak over 520 languages.

Despite having only a population of 200,000 people, Samoa is known for having a highly successful Rugby team, competing at every Rugby world cup since 1991 and often beating teams from countries with upwards of ten times its own population. Samoa, together with Fiji, Nauru, Palau, and Tuvalu, submitted a working paper to a UN working group in Geneva in 2016 in which they argued that ‘the debate should no longer be about whether a global ban on nuclear weapons is necessary, but rather how we can achieve it and what provisions it should contain’. This stems from these countries lived experience of nuclear weapons testing within the pacific.

San Marino  Flag: San Marino on Twitter

Vietnam, also known as the Socialist Republic of Vietnam, is a country in Southeast Asia located at the eastern edge of the Indochinese peninsula. Vietnam fought a war for independence from both the French and then the United States during the 1960s and 1970s. During that time a top American military commander, William Westmoreland, prepared to transfer nuclear weapons to South Vietnam to use against North Vietnam troops. Thankfully, this was prevented by then US President, Lyndon B Johnson, but many people around the world remain unaware of how close the conflict came to turning nuclear. US President Nixon was also in favour of using nuclear weapons against Vietnam, but was deterred by advisors.


Toward a nuclear-free future

The diverse collection of countries which have come together to oppose nuclear weapons can be considered a feat of peace-making and diplomacy. Around the world there are ‘Nuclear-free zones’ established by treaties signed by many of the countries above, such as the Treaties of Tlatelolco, the Treaty of Bangkok, the Treaty of Pelindaba, the Rarotonga treaty and Treaty of Semipalatinsk which establish Latin America and the Caribbean, Southeast Asia, Africa, the South Pacific and Central Asia as nuclear-free zones respectively.

Similar agreements have established Nuclear-Weapon Free Areas in the Antarctic, on the Sea-Bed and in Outer Space. Nuclear Weapons-Free Zones are highly successful forms of collective security across large parts of the world, including almost the entire southern hemisphere.

While the nations of the global south have led the way on this front, this has even inspired change in nuclear-armed states themselves where local councils have voted for their cities to become ‘nuclear ban communities’, the first one in the UK being designated by Manchester City Council in the 1980s, with many more existing today. Be sure to check online to see whether you live in a ‘nuclear ban community’ and if not, maybe you can encourage your council to become one: https://staging.cnduk.org/nuclear-ban-communities/, https://cities.icanw.org/
