Another development that may have slipped past you while the spending review was underway came from the United States.
Reuters, among other, have been told that the Trump administration is carrying a review of the landmark AUKUS agreement.
This is a deal between Australia, the UK and the US announced under Boris Johnson and Joe Biden.
It is supposed to help Australia acquire nuclear-powered submarines, as well as other defence partnerships.
While some have reported concerns in Canberra and London due to the decision, on the record the UK government seems a bit more sanguine.
They have pointed out the Labour government did a review when they came to power.
A Foreign Office spokesperson said: "AUKUS is a landmark security and defence partnership with two of our closest allies.
"It is one of the most strategically important partnerships in decades, supporting peace and security in the Indo-Pacific and Euro-Atlantic, while also delivering jobs and economic growth in communities across all three nations.
"It is understandable that a new administration would want to review its approach to such a major partnership, just as the UK did last year.
"The UK will continue to work closely with the US and Australia at all levels to maximise the benefits and opportunities which AUKUS presents for our three nations."
A US official told Reuters that the idea is to ensure the "initiative of the previous administration is aligned with the president's America first agenda".
