Golden Dome over America: How this Trump-proposed missile shield will work
President Donald Trump has announced a $175 billion missile defense initiative dubbed the Golden Dome, a multi-layered shield designed to protect the US from advanced threats.The shield is aimed at thwarting incoming hypersonic missiles, drones, and space-based attacks.Proposed by defense giant Lockheed Martin, the system aims to integrate ground and space-based technologies to detect, track, and intercept projectiles at every stage of flight, from launch to impact.

The Golden Dome revives the ambition of Ronald Reagan's Strategic Defense Initiative (SDI), colloquially known as "Star Wars," but with 21st-century technology.Lockheed Martin, the project's lead contractor, describes it as a "Manhattan Project-scale mission" combining existing missile defense systems with next-gen innovations like space-based interceptors, AI-driven sensors, and laser weapons.The system will deploy hundreds of satellites for real-time threat detection and leverage combat interceptors such as the Terminal High Altitude Area Defense (THAAD) and Aegis systems to target the incoming missiles, drones.

advertisementHOW IT WORKSThe Golden Dome's architecture includes:Space-based sensors: Satellites to detect missile launches globally, even in their boost phase.Interceptor networks: Ground- and space-based missiles to neutralise threats mid-flight.AI-powered command systems: Rapid data analysis to coordinate responses across the defense network.Lockheed CEO Jim Taiclet emphasized the system's scalability, stating it will integrate "the best of American industry" to counter evolving threats, including AI-driven drone swarms.BIG BUCKS NEEDEDTrump claims the Golden Dome will be operational by January 2029, with an initial $25 billion allocated through the "One Big Beautiful Bill Act". However, experts question the feasibility of this timeline, given the complexity of deploying untested space-based technologies.Defense Secretary Pete Hegseth clarified the system will defend against both conventional and nuclear threats, though technical specifics remain scarce.The project has sparked debates over cost, space militarisation, and nuclear proliferation.

While Trump touted a "success rate close to 100%", critics argue the $175 billion price tag underestimates long-term expenses, with independent analysts projecting costs exceeding $500 billion.advertisementLockheed Martin's proposal faces scrutiny for its reliance on emerging technologies, such as laser defenses, which remain in experimental stages. Meanwhile, the involvement of SpaceX—given CEO Elon Musk's advisory ties to Trump—has raised concerns about conflicts of interest.Meanwhile, the involvement of SpaceX—given CEO Elon Musk's advisory ties to Trump—has raised concerns about conflicts of interestIf realized, the Golden Dome would mark the first US weapon system stationed in space, reshaping global defense dynamics.

Iran says no sanctions relief in US nuclear proposal
Iran's parliament speaker said on Sunday that the latest US proposal for a nuclear deal does not include the lifting of sanctions, state media reported as negotiations appear to have hit a roadblock. The two foes have held five rounds of Omani-mediated talks since April, seeking to replace a landmark agreement between Tehran and world powers that set restrictions on Iran's nuclear activities in return for sanctions relief, before US President Donald Trump abandoned the accord during his first term in 2018. In a video aired on Iranian state TV, parliament speaker Mohammad Bagher Ghalibaf said that "the US plan does not even mention the lifting of sanctions". He called it a sign of dishonesty, accusing the Americans of seeking to impose a "unilateral" agreement that Tehran would not accept. "The delusional US president should know better and change his approach if he is really looking for a deal," Ghalibaf said. On May 31, after the fifth round of talks, Iran said it had received "elements" of a US proposal, with officials later taking issue with "ambiguities" in the draft text. The US and its Western allies have long accused the Islamic republic of seeking to acquire nuclear weapons, a charge Iran has consistently denied, insisting that its atomic programme was solely for peaceful purposes. Key issues in the negotiations have been the removal of biting economic sanctions and uranium enrichment. Tehran says it has the right to enrich uranium under the nuclear Non-Proliferation Treaty, while the Trump administration has called any Iranian enrichment a "red line". Trump, who has revived his "maximum pressure" campaign of sanction on Iran since taking office in January, has repeatedly said it will not be allowed any uranium enrichment under a potential deal. On Tuesday, Iran's top negotiator, Foreign Minister Abbas Araghchi, said the country "will not ask anyone for permission to continue enriching uranium". According to the UN nuclear watchdog, the International Atomic Energy Agency , Iran is the only non-nuclear-weapon state in the world that enriches uranium up to 60 percent still short of the 90 percent threshold needed for a nuclear warhead. Iran's supreme leader Ayatollah Ali Khamenei on Wednesday rejected the latest US proposal and said enrichment was "key" to Iran's nuclear programme. The IAEA Board of Governors is scheduled to meet in Vienna later this month and discuss Iran's nuclear activities. pdm/ami

Russia Says Its Forces Reach Ukraine's Dnipropetrovsk Region
Russia said its ground forces crossed into Ukraine's central Dnipropetrovsk region for the first time, a symbolic milestone in their grinding offensive as prospects for a US-brokered ceasefire remain elusive. The claim couldn't be independently verified, and Ukraine's southern defense forces, in response, said its troops were 'holding their section of the front' while involved in a 'tense' situation. Units of the 90th tank regiment crossed the western border of Donetsk into the adjacent Dnipropetrovsk region, Russia's defense ministry said Sunday on its Telegram channel. It would be the first time Moscow's land forces have set foot in one of Ukraine's most populous and industrialized areas since the start of the large-scale invasion more than three years ago. The value of reaching the edge of the region appears mostly symbolic, as Kremlin troops are still more than 140 kilometers away from the regional capital of Dnipro, which is also protected by the river of the same name and its system of estuaries. Yet pushing further west could fuel the aggressive posture taken by President Vladimir Putin, who's sticking with maximalist goals in Ukraine while resisting US President Donald Trump's efforts to bring him to the negotiating table. Dnipro is Ukraine's fourth-largest city, behind Kyiv, Kharkiv and Odesa, with a pre-war population of about 1 million people. The advance takes place at a time Russia has recently seized small amounts of territory near the nations' border in Ukraine's northeastern Sumy region. It also brings the war onto the soil of two provinces which so far haven't been officially earmarked for annexation by Putin. The Russian president has demanded that Kyiv surrender all of the Donetsk, Luhansk, Zaporizhzhia, and Kherson provinces, which Russia illegally annexed in 2022 but doesn't fully control. That's in addition to Crimea, which Kremlin forces illegally annexed in 2014. Russia's slow-going ground war has picked up speed recently, with its capturing a small amount of territory in late May. Before the war's start, Dnipropetrovsk was Ukraine's second most populated region after Donetsk, and is the second-largest territory by land mass after the Odesa region. It's home to a major steel industry, coal mining and machine building and is an important logistics hub for the army.

China clears rare earths export applications, not clear if Indian companies included
China's decision in April to halt exports of a wide range of rare earths and related magnets disrupted global supply chains, affecting industries from automotive and aerospace to semiconductors and defence read more Miners are seen at the Bayan Obo mine containing rare earth minerals, in Inner Mongolia, China. File image/ Reuters China said Saturday (June 7) it is prepared to accelerate the approval process for rare earth exports to European Union companies and will issue a final ruling on its trade probe into EU brandy imports by July 5. The developments come amid broader efforts to resolve ongoing trade tensions between Beijing and Brussels. Talks were held earlier this week in Paris between Chinese Commerce Minister Wang Wentao and EU Trade Commissioner Maros Sefcovic, China's Commerce Ministry said in a statement. STORY CONTINUES BELOW THIS AD Price commitment discussions on Chinese-made electric vehicles exported to the EU have also reached the final phase. 'Efforts from both sides are still needed,' the ministry said. The ministry added that China 'was willing to establish a green channel for qualified applications to speed up the approval process' for rare earth exports. It also noted that Beijing recognised rising demand for rare earth materials across sectors including electric vehicles and robotics and that it 'was willing to further strengthen communication and dialogue with relevant countries' on the matter. Rare earths and trade friction China's decision in April to halt exports of a wide range of rare earths and related magnets disrupted global supply chains, affecting industries from automotive and aerospace to semiconductors and defence. The move has become a flashpoint in EU-China trade relations. The ministry said it 'attached great importance to the EU's concerns' and indicated it would work to resolve the bottleneck in a timely manner. Brandy duties under review China's anti-dumping duties of up to 39 per cent on European brandy, particularly French cognac, were implemented shortly after the EU imposed tariffs on Chinese electric vehicles. The Chinese measures have impacted major French producers including LVMH's Hennessy, Pernod Ricard's Martell, and Remy Cointreau. French President Emmanuel Macron previously accused Beijing of 'pure retaliation' over the duties. Beijing had initially planned to announce a final decision on the brandy investigation in January, later postponing it to April and now July 5. On Saturday, the Commerce Ministry confirmed that French firms and industry associations had submitted price commitment proposals and that investigators had reached agreement on key terms. 'Chinese authorities are now reviewing the complete text on those commitments and will issue a final announcement before July 5,' the statement said. Electric vehicle negotiations ongoing The European Commission said in April it was working with Beijing to consider a minimum price framework for Chinese electric vehicles in lieu of the tariffs imposed in 2023. China's Commerce Ministry said the EU also proposed examining 'new technical paths' related to electric vehicles, and that China was now evaluating those ideas. Wang also told Sefcovic that China hoped the EU would 'meet us halfway and take effective measures to facilitate, safeguard and promote compliant trade in high-tech products to China.'
