US, UK and Australia forge military alliance to counter China

The US, UK and Australia are setting up a trilateral security partnership aimed at confronting China, which will include helping Australia to build nuclear-powered submarines.

The initiative, called Aukus, was announced jointly by President Joe Biden and prime ministers Boris Johnson and Scott Morrison, following US briefings which described the agreement as binding the three English-speaking countries together.

Boris Johnson, the UK prime minister, said they were “natural allies” even though “we may be separated geographically” and said the alliance would create “a new defence partnership and driving jobs and prosperity”.

A senior US official described the agreement as “a fundamental decision, that binds decisively Australia to the United States and Great Britain for generations”.

Teams from the three countries will work together over the next 18 months on a plan for the project, which would make Australia only the seventh country in the world to field submarines propelled by nuclear reactors.

Australia insists that it has no intention of pursuing nuclear weapons and will abide by the Nuclear Non-Proliferation Treaty (NPT), but critics said the decision could still indirectly spur the proliferation of weapons.

Any new nuclear-powered submarines, which are powered with the help of enriched uranium, will take years – possibly over a decade – to develop. But once at sea, they will put Australia’s currently diesel-powered navy on a technological par with China’s navy, the world largest.

As well as cooperation on naval technology, the partnership will involve closer alignment of regional policies and actions, and greater integration of the militaries and the defence industries of the three allies. The three also intend to work together on cyber-warfare and on artificial intelligence capabilities.

“I think this is an historic announcement,” a senior US official said ahead of a formal announcement by Biden, Johnson and Morrison. “This is designed not only to strengthen our capabilities in the Indo-Pacific, but to link Europe, and particularly Great Britain, more closely with our strategic pursuits in the region as a whole.”

British officials said they hoped the UK would benefit from defence companies supplying technology to Australia. Derby-based Rolls-Royce supplies reactors for Royal Navy submarines, which are eventually decommissioned in the UK when spent. But it is not yet clear how the Australian reactors will be supplied or decommissioned.

The formation of Aukus comes at a time of rising tensions, especially over the South China Sea and Taiwan. A new book about the last weeks of the Donald Trump administration said that in late 2020 the US became concerned that China was increasingly convinced it would be the target of a pre-emptive attack.

According to Peril, by Washington Post journalists Bob Woodward and Robert Costa, the chairman of the joint chiefs of staff, Gen Mark Milley called his Chinese counterpart, Gen Li Zuocheng, twice to reassure him that no attack would happen, and that Milley would personally give a warning if Trump issued such an order.

In July, the UK’s new aircraft carrier, the Queen Elizabeth, arrived in the South China Sea, the focal point of US-Chinese tensions, triggering denunciations from Beijing. The US defence secretary, Lloyd Austin, welcomed the deployment at the time but wondered “are there areas that the UK can be more helpful in other parts of the world”.

A senior US official suggested that the UK government had pushed for a heightened role in the region.

“Great Britain is very focused on the concept of global Britain, and their tilt is about engaging much more deeply with the Indo-Pacific and this is a down payment on that effort,” the official said.

Before now, the US has only shared nuclear propulsion technology with the UK, in an arrangement dating back to the 1958, but a senior US official said “This is a unique set of circumstances.”

Nuclear power will allow Australian attack submarines to remain at sea for as long as five months and operate more quietly than the country’s existing Collins class diesel powered vessels, allowing them to better evade enemy detection.

Senior US officials briefing reporters before the announcement did not mention China, preferring to speak generally about “sustaining and improving deterrence”, but left little doubt which power Aukus was supposed to deter. British officials used similar language, arguing the deal was “not about one country”.

Alliance with Australia and US a ‘downpayment on global Britain’

Some critics of the agreement warn that it sets a dangerous precedent for countries to exploit a loophole in the NPT. The treaty allows non nuclear weapon countries to build nuclear-powered submarines, and to remove the fissile material they need for the submarine reactors from the stockpile monitored by the global watchdog, the International Atomic Energy Agency, opening up the possibility it could be diverted to making weapons. Australia would be the first country to make use of the loophole.

“My concern is not that Australia would misuse the nuclear material we give them and use the loophole to build nuclear weapons,” James Acton, co-chair of the nuclear policy programme at the Carnegie Endowment for International Peace, said. “My concern is it sets a terrible precedent that other countries could abuse. “Iran is the obvious example here. We would go batshit if Iran removed nuclear material from safeguards.”

David Cullen of the Nuclear Information Service, said: “This has only happened once before in history, when the US helped the UK develop its first nuclear-powered submarines.

“What’s interesting is that the US appears to have thrown the UK a bone by allowing Britain to help design and build the new Australian submarines. The question will be how will the Australians be supplied and whether they want to develop their own nuclear capability to enrich uranium fuel.”

British sources said the conversations about the nuclear power deal were initiated by the Australians in March.
