Apart from the five permanent members of the UN security council (the US, Russia, China, France, and Britain), which are all nuclear powers, around 25 other countries have sought to obtain nuclear weapons, say international analysts.
Israel, India, Pakistan, and South Africa are known to have succeeded, though South Africa voluntarily relinquished its bomb in the 1990s, a unique event.
North Korea is feared to be building a bomb, Saddam Hussein's Iraq tried and failed, and Iran is said to be creating the capacity.
Japan has the fissile material and the know-how to develop one quickly. Other countries occasionally rumored to have nuclear ambitions include Brazil, Argentina, Libya, and Algeria.
Israel
It has never officially declared itself a nuclear power but is by some distance the mightiest nuclear power outside the Big Five, with the first prime minister, David Ben-Gurion, inaugurating the project in the mid-1950s in great secrecy. It had a rudimentary device by the late 60s. Mordechai Vanunu, a nuclear technician, famously blew the whistle on the programme in 1986 and was imprisoned.
France is believed to have supplied Israel secretly with a nuclear reactor and equipment for extracting weapons-grade plutonium from spent nuclear fuel in the 1950s.
Israel is estimated to have stockpiles of more than half a tonne of plutonium and an unknown quantity of weapons-grade high-enriched uranium. The plutonium stockpile is more than the combined total held by the other non-Big Five nuclear powers. Experts estimate that Israel has around 200 nuclear devices.
India
For decades India pursued the bomb using a plutonium extraction plant and two heavy water reactors which produce plutonium. The Indian effort was based at the Bhabha atomic research centre outside Bombay. It went public in 1974 when a plutonium-core fission bomb was tested in the Rajasthan desert.
Analysts estimate that the Indian nuclear arsenal has up to 70 devices.
Pakistan
The Indian successes triggered a nuclear arms race on the sub- continent. The father of the Pakistani bomb, Abdul Qader Khan, worked in the Netherlands for what became the Anglo-Dutch-German Urenco company specializing in uranium enrichment.
He is said to have stolen centrifuge designs for uranium enrichment and inaugurated the crash Pakistani programme. The same designs have been used at the Iranian facility at Natanz, feeding speculation that the Iranians obtained equipment and help from Islamabad.
The Pakistanis built the Kahuta enrichment plant using the Urenco designs to produce weapons-grade uranium, and are believed to have obtained weapons designs from China. Pakistan announced it had the bomb in 1998.
Pakistan is the only country known with certainty to have a bomb developed from a programme started after the nuclear non-proliferation treaty came into force in 1970. It is believed to have at least 700kg of weapons-grade uranium and a small quantity of plutonium stockpiled and to have up to 15 nuclear devices.
North Korea
The current crisis over North Korea's nuclear ambitions came to a head last year when Pyongyang cut off relations with the UN watchdog, the Vienna-based International Atomic Energy Agency, and said it would not observe the non-proliferation treaty.
The jury is still out on whether North Korea has the bomb. It said last month it could test a nuclear device when it wanted. Washington believes it may have two.
Multilateral efforts are under way to defuse the crisis, which is having the knock-on effect in Japan of encouraging the only country to have been hit by an atomic bomb to build its own. Japan has a large civil nuclear power sector, ample stockpiles of plutonium, and the technological and scientific resources to obtain a nuclear bomb swiftly.
Iran
A dripfeed of revelations from UN inspectors over recent months is hardening suspicions that Tehran is bent on acquiring nuclear weapons, or creating the wherewithal. It was last week presented with an ultimatum by the UN: reveal all by the end of next month and allow unrestricted inspections.
Recent discoveries and question marks include the tracing of two different types of weapons-grade uranium at an underground uranium enrichment centre being built in central Iran, the disclosure that the programme goes back to 1985 and not 1997 as previously stated, evidence of uranium metal conversion testing -- needed for weapons but not for power stations -- and substantial rebuilding at a suspect Tehran facility, apparently to frustrate UN inspections and environmental sampling for radioactive materials.
LANDMARK CASE: ‘Every night we were dragged to US soldiers and sexually abused. Every week we were forced to undergo venereal disease tests,’ a victim said More than 100 South Korean women who were forced to work as prostitutes for US soldiers stationed in the country have filed a landmark lawsuit accusing Washington of abuse, their lawyers said yesterday. Historians and activists say tens of thousands of South Korean women worked for state-sanctioned brothels from the 1950s to 1980s, serving US troops stationed in country to protect the South from North Korea. In 2022, South Korea’s top court ruled that the government had illegally “established, managed and operated” such brothels for the US military, ordering it to pay about 120 plaintiffs compensation. Last week, 117 victims
‘HYANGDO’: A South Korean lawmaker said there was no credible evidence to support rumors that Kim Jong-un has a son with a disability or who is studying abroad South Korea’s spy agency yesterday said that North Korean leader Kim Jong-un’s daughter, Kim Ju-ae, who last week accompanied him on a high-profile visit to Beijing, is understood to be his recognized successor. The teenager drew global attention when she made her first official overseas trip with her father, as he met with Chinese President Xi Jinping (習近平) and Russian President Vladimir Putin. Analysts have long seen her as Kim’s likely successor, although some have suggested she has an older brother who is being secretly groomed as the next leader. The South Korean National Intelligence Service (NIS) “assesses that she [Kim Ju-ae]
In the week before his fatal shooting, right-wing US political activist Charlie Kirk cheered the boom of conservative young men in South Korea and warned about a “globalist menace” in Tokyo on his first speaking tour of Asia. Kirk, 31, who helped amplify US President Donald Trump’s agenda to young voters with often inflammatory rhetoric focused on issues such as gender and immigration, was shot in the neck on Wednesday at a speaking event at a Utah university. In Seoul on Friday last week, he spoke about how he “brought Trump to victory,” while addressing Build Up Korea 2025, a conservative conference
China has approved the creation of a national nature reserve at the disputed Scarborough Shoal (Huangyan Island, 黃岩島), claimed by Taiwan and the Philippines, the government said yesterday, as Beijing moves to reinforce its territorial claims in the contested region. A notice posted online by the Chinese State Council said that details about the area and size of the project would be released separately by the Chinese National Forestry and Grassland Administration. “The building of the Huangyan Island National Nature Reserve is an important guarantee for maintaining the diversity, stability and sustainability of the natural ecosystem of Huangyan Island,” the notice said.
