Nuclear weapons

Iranian President Masoud Pezeshkian addressed the 80th UN General Assembly, outlining Iran's positions on nuclear weapons, Israel and regional security. He is reported to have drawn clear red lines for Tehran, insisting Iran will not pursue nuclear arms while defending its right to respond to Israeli actions and regional pressure. The speech is drawing wide attention as tensions over Iran's nuclear program and the conflict with Israel remain high.

North Korea, formally the Democratic People's Republic of Korea, has told the United Nations that its status as a nuclear-armed state is irreversible and that it rejects outside pressure to abandon its weapons programme. The declaration signals Pyongyang's continued refusal of denuclearisation talks and is likely to draw condemnation from the US, South Korea, Japan and other governments backing sanctions and diplomatic pressure.

French news programme 24H Pujadas on LCI is covering a US alert about Russia allegedly developing or deploying nuclear weapons in orbit. The report examines warnings from American officials about a possible space-based nuclear capability, a scenario that would violate the Outer Space Treaty and raise major security concerns for Western allies.

North Korea has accused the United States of creating a 'worse crisis' in the global nuclear order, using the claim to justify its own nuclear arsenal. The statement, reported by Yonhap News Agency, repeats Pyongyang's long-standing argument that American hostility and pressure leave it no choice but to expand and maintain its weapons program. It comes amid continued tensions over North Korea's weapons development and stalled diplomatic efforts.

Japan's defense minister has once again drawn attention to the country's 'nuclear taboo', questioning long-standing constraints on discussing nuclear weapons policy. The comments come from the only nation to have suffered atomic bombings, where official debate about nuclear options has long been politically sensitive. The remarks have reignited discussion at home and abroad about Japan's defense posture and regional security.

Donald Trump says Iran is prepared to declare it will never develop nuclear weapons, a statement reported by regional outlets and drawing attention amid ongoing tensions over Tehran's nuclear programme. The claim, if confirmed, would mark a significant step in negotiations, though Iran has not been shown to have formally issued such a commitment.

A potential agreement between Donald Trump and Kim Jong-un on North Korea's nuclear programme could leave South Korea still exposed to Pyongyang's nuclear threat, according to Korea JoongAng Daily. The concern is that a US-North Korea deal focused on missiles capable of reaching the United States might leave shorter-range weapons threatening South Korea intact, prompting debate in Seoul over its security and possible independent deterrent options.

The Pentagon is reportedly weighing a new nuclear strategy aimed at deterring regional conflicts rather than solely major-power war. The reported shift would adjust how US nuclear weapons fit into plans for limited, regional contingencies. The Globe Post reported the story, but no further details on the proposals, their scope, or official confirmation have emerged so far, and reaction from lawmakers, allies, or arms-control groups has not been recorded.

US officials say that if Iran acquired nuclear weapons, no country could prevent it from controlling the Strait of Hormuz, the chokepoint through which a large share of the world's oil passes. The warning underscores Washington's argument for preventing Iran from developing nuclear arms amid ongoing tensions over its nuclear programme.

A foreign and security policy analysis argues that living with nuclear weapons is once again a central challenge for international politics. Amid renewed great-power rivalry, eroding arms control treaties and ongoing conflicts involving nuclear-armed states, policymakers and commentators are debating how deterrence, disarmament and civilian protection can coexist in a more dangerous world.

US Secretary of State Marco Rubio said Iran would 'blackmail the world' if it acquired a nuclear weapon, reinforcing Washington's position that Tehran must never obtain one. The remark adds to ongoing tensions over Iran's nuclear programme and the future of diplomatic efforts to curb it, with officials framing the issue as a global security threat.

Donald Trump said the United States will ensure the Strait of Hormuz remains open and declared that Washington will not allow Iran to acquire a nuclear weapon. The remarks come amid ongoing tensions in the Persian Gulf, where Iran has previously threatened to close the strategically vital shipping lane used for a large share of the world's oil.

Reports describe a new nuclear age as more countries weigh acquiring or expanding nuclear options. The discussion points to shifting security concerns and weakening confidence in existing deterrence arrangements, prompting renewed debate about proliferation. Commentators are assessing what this trend could mean for global stability and arms control efforts, warning that growing interest in nuclear capability risks a wider race for such weapons.

The Middle East Institute examines whether Ankara could pursue nuclear weapons in the wake of the war involving Iran. The piece explores how a weakened Iranian deterrence and regional insecurity may reshape Turkey's strategic calculus, long balancing between NATO membership and indigenous defence ambitions, and what that would mean for non-proliferation efforts.

US Secretary of State Marco Rubio defended the decision to go to war with Iran, arguing that President Trump's actions stopped Tehran from developing nuclear weapons and becoming what he called a 'North Korea in the Middle East'. His remarks come amid ongoing debate over the strikes and their lasting impact on Iran's nuclear programme and regional stability.

Defence analysts argue that a Chinese attempt to seize Taiwan could prompt Japan to abandon its non-nuclear posture and develop nuclear weapons. Commentary published by RealClearDefense and ASPI's Strategist suggests such a move would be, as the headline puts it, 'revolting for the CCP', since a nuclear-armed Japan would fundamentally alter Beijing's security calculations and regional power balance.

The U.S. Navy is moving forward with development of the W93, a new nuclear warhead intended for submarine-launched ballistic missiles. The programme, run with the Department of Energy's nuclear weapons complex, is part of efforts to modernise the sea-based leg of the U.S. nuclear triad, replacing warheads carried on Trident II D5 missiles aboard ballistic missile submarines.

US Secretary of State Marco Rubio is defending the decision to strike Iran, saying the president prevented Iran from becoming 'a North Korea in the Middle East'. His comments frame the military action as necessary to stop Tehran acquiring nuclear weapons, and are likely to fuel ongoing debate in the US and abroad over the legality and wisdom of the strikes and Iran's actual nuclear progress.

Bill Gates told the Ezra Klein Show that artificial intelligence is such a transformative technology it 'makes nuclear weapons look like nothing'. The remark is drawing wide attention online, fueling debate over whether AI's risks and rewards truly dwarf those of nuclear arms, and what such a warning from one of tech's most prominent figures means for regulation and safety.

A new commentary argues that policymakers are leaning too heavily on Manhattan Project-era nuclear analogies when thinking about artificial intelligence, and that this framing is distorting AI governance. The author contends that treating AI like nuclear weapons encourages centralized, secrecy-driven approaches that fit poorly with how AI technology actually develops and spreads, and calls for policy grounded in AI's realities rather than Cold War precedent.

A new initiative called Neighbors Against Nukes has been introduced, focused on opposing nuclear weapons. Details about the group's founders, location and specific aims are limited so far, but the launch has drawn attention in arms control and nuclear policy circles, where public campaigns against nuclear arsenals regularly attract debate.

A new commentary argues that AI companies could learn from how nuclear weapons programs developed safety protocols, international treaties and control regimes after 1945. The author suggests parallels between managing dangerous emerging technologies and today's race to build powerful artificial intelligence, warning that safety measures should not be an afterthought as capabilities advance.

A large multiplayer experiment put 100 people on a single game server with nuclear weapons enabled, and it drew close to a million engagements. Viewers are reacting to the chaos that follows when dozens of players gain access to devastating firepower at once, with many debating how quickly the server would descend into all-out destruction.

The United Nations convened its first meeting dedicated to assisting victims of nuclear weapons use and testing. The session follows growing international momentum around the Treaty on the Prohibition of Nuclear Weapons, which obliges member states to aid affected communities in places like the Marshall Islands, Kazakhstan and Japan. Arms control advocates welcomed the step as long-overdue recognition of hibakusha and other survivors.

An interfaith panel has issued a call for the abolition of nuclear weapons, arguing against fatalistic acceptance of their continued existence. The panel's message, promoted by the International Campaign to Abolish Nuclear Weapons, stresses that disarmament is a moral and practical choice rather than an impossible goal, and urges people of different faiths to work together toward eliminating nuclear arms worldwide.
