Trump's 'Golden Dome' missile shield could cost hundreds of billions
Your web browser is no longer supported. To improve your experience update it here The Pentagon has submitted small, medium and large options to the White House for developing "Golden Dome," US President Donald Trump's vision for a cutting-edge missile shield that can protect the country from long-range strikes that will likely cost hundreds of billions of dollars, according to multiple sources familiar with the plans. Trump is expected to announce his preferred option – and its price point – in the coming days, a decision that will ultimately chart a path forward for funding, developing and implementing the space-based missile defence system over the next several years. Whatever option Trump opts for, it won't be cheap; $US25 billion ($39 billion) has been carved out in next year's defence budget for the system, but the Congressional Budget Office has estimated the US could have to spend more than $US500 billion – over the course of 20 years – to develop a viable Golden Dome.

The US Department of Defence "has developed a draft architecture and implementation plan for a Golden Dome system that will protect Americans and our homeland from a wide range of global missile threats," chief Pentagon spokesman and senior adviser Sean Parnell told CNN in a statement. "The Secretary of Defence and other Department leaders have engaged with the President to present options and look forward to announcing the path forward in the coming days," Parnell added. A key part of the implementation plan will be the establishment of a direct reporting program manager – also known as a "golden dome czar" – who can oversee the development and deployment of the highly complex system, according to three sources familiar with the conversations. General Michael A. Guetlein, vice chief of space operations at the US Space Force, is under close consideration for the role, the sources said, noting he is a four-star general with experience in the procurement of missile defence systems and emerging space-based capabilities.

Another person with direct knowledge of the options said the system would ultimately encompass about 100 programs, many of which already live within the Defence Department or are in development. The one "entirely new" aspect would be the command and control and integration layer of the architecture, this person said. "There are a lot of different flavours of what this could look like," said a senior congressional official familiar with the Pentagon's proposed plans. A comprehensive missile defence shield is a concept the US has pursued for decades but never realised because of gaps in technology and cost. Trump has repeatedly insisted the US needs a missile defence program similar to Israel's Iron Dome, but the systems are orders of magnitude apart. In practical terms, the comparison is less apples to oranges, and more apples to aircraft carriers. A battery of Israel's Iron Dome missile defence system, deployed to intercept rockets.

The Defense Intelligence Agency recently released an unclassified assessment titled "Golden Dome for America," underscoring how US adversaries such as China, Russia, Iran and North Korea can target the American homeland with a variety of ballistic missiles, long-range cruise missiles, bombers and hypersonic missiles. The core policy decision for Trump largely centers on next-generation capabilities to defend the US against ICBMs or hypersonic threats, the congressional official added, noting it is clear Golden Dome will require "a "significant research and development effort." Developing such a complex system will require establishing a network of government agencies and private contractors, the makeup of which remains unclear at this early stage, multiple sources familiar with the planning process said.

‘Potential agroterrorism weapon': US charges Chinese researchers with fungus smuggling
Washington: The US Justice Department has charged two Chinese researchers accused of trying to smuggle a fungus into America, bringing the case as the government pushes to keep more Chinese students out of the country. The students, Yunqing Jian, 33, and Zunyong Liu, 34, were in a romantic relationship in July, when US authorities say Liu arrived in the US carrying small bags of the fungus Fusarium graminearum, which causes a disease that can cripple wheat, barley, corn and rice. The disease, head blight, is a familiar problem for American farmers, particularly in northern and eastern states, according to research funded by the US Agriculture Department that has tracked it in 32 states last year. The fungus can be particularly damaging to winter wheat crops. Jian was arrested and booked in the federal courthouse in Detroit; Liu is believed to be in China. The criminal charges come as tensions mount between the US and China over the Trump administration's vow to 'aggressively' revoke student visas for Chinese nationals. Such students, the administration says, could siphon off sensitive technology or trade secrets from American labs for the benefit of their home country. Jerome F. Gorgon jnr, the interim US attorney in Detroit, said the researchers' alleged actions amounted to 'the gravest national security concerns'. He said they had tried to bring 'a potential agro-terrorism weapon' into 'the heartland of America'. For decades, US national security officials have worried about – and sometimes arrested – Chinese academics suspected of stealing scientific data from American universities and businesses. The Trump administration's new push goes further by stripping an unspecified number of students of visas.

Australia spared Trump tariff letter as Ley says Albanese should secure special deal
Australia has been spared a letter from the Trump administration demanding countries cut trade barriers to US goods as the White House prepares to reinstate its 'Liberation Day' tariffs, but has not secured a UK-style exemption to increased steel and aluminium import taxes. Opposition Leader Sussan Ley pushed Prime Minister Anthony Albanese to get the same treatment for Australia that British Prime Minister Keir Starmer won for UK steel to prevent it from being subject to a 50 per cent tariff in the US, saying the opposition would work with the government to make it happen. 'President [Donald] Trump's tariffs on our steelmakers are not in the spirit of our century-old partnership and we urge the Americans to give Australia a fair go and remove them,' Ley said. Trade Minister Don Farrell met his US counterpart Jamieson Greer in Paris overnight as Albanese prepares to hold his first meeting with Trump later this month. The meeting is expected to be dominated by Trump's tariff war and US requests for its allies to boost defence spending. The United States Trade Representative, the office primarily responsible for trade matters, sent a letter to countries asking them to provide their best offer for a trade deal by Wednesday, US time. The Trump administration confirmed the missive, which was first reported by Reuters. The letter suggests fresh urgency from the Trump administration as it looks to settle trade deals with partners ahead of July 8, which is when the 90-day 'pause' on Trump's so-called reciprocal tariffs expires. An Australian government spokeswoman said Australia did not receive the letter because it was only sent to nations with a higher tariff rate than the baseline 10 per cent rate. 'Australia is in the lowest 'baseline' tariff tier of 10 per cent,' she said. 'As such, the US administration has confirmed Australia has not been sent a letter. 'We continue to engage with the US on our trade interests. Trade Minister Farrell met with his US counterpart today in Paris and pressed for the removal of unjustified tariffs imposed on Australian goods.'
