Donald Trump declared Ukraine had started the war with Russia and labelled its leader Volodymyr Zelenskyy, a dictator. 

Trump’s vice president JD Vance has thrown his support behind far-right parties in Germany.

At the same time, talks on ending the war in Ukraine began with only the US and Moscow at the table. 

It was a week where we saw an extraordinary shift in American foreign policy, which led to European leaders holding crisis talks.

The RBA’s interest rate cut has been largely welcomed but it won’t make much difference to the family budget. 

So, why is there speculation that the Prime Minister Anthony Albanese might call an early election because of it?

Today, we speak to someone whose life was upended by the 13 interest rate rises and to a pollster about why Labor’s finding it hard to convince voters it’s not to blame for the financial pain.

Within hours of its release, the Chinese-owned AI chatbot called DeepSeek became one of the most downloaded apps in the world.

Most commentators say it performs just as well as the market-leader ChatGPT, but should we be wary of it? 

Each time users open it up and type something into that box, the app is gathering information and sending it back to servers in China.

Emily’s son loved sport, animals, reading and music, but when he turned 16, everything changed. 

He started to get obsessed by politics and thought the country was headed in the wrong direction. 

It wasn’t until his mother saw a photo of her son on the news that she realised he’d joined a neo-Nazi group. 

Emily hopes a deradicalisation program will keep her son safe from extremists, but there’s concern about the availability and quality of the services. 

Today, Four Corners reporter Avani Dias on Emily’s case and a rise in extremism among young Australians.

Donald Trump says negotiations to end the war in Ukraine have begun and both Russia and Ukraine want peace. 

The US president chose to call the instigator of the war Vladimir Putin first to discuss a potential deal, raising fears he’ll push Ukraine to the sidelines. 

The US is already insisting that Ukraine can’t restore its territory to what it had in 2014 and it says Ukraine won’t join the NATO military alliance. 

Today, international relations expert Rajan Menon on what peace might really look like under Trump.

Donald Trump says no nation will be exempt, although there’s a prospect of Australia winning a rare reprieve from hefty tariffs being imposed on all steel and aluminium imports to the United States. 

Australia’s Prime Minister Anthony Albanese has been on a phone call with the US president, urging him to exempt Australia from the 25 per cent import tax. 

The key argument is that Australia imports a lot more from the US than it sells there. 

Today, economist Susan Stone on the latest front in the trade wars and what it means for us.

Elon Musk thinks the peak US foreign aid agency is ‘evil’ and so in his powerful position as Donald Trump’s cost cutter he’s getting rid of it.

USAID was set up by President John F. Kennedy and supports humanitarian projects across the globe. 

Already there are reports of people dying on the Thai-Myanmar border when a US supported hospital in a refugee camp was abruptly shut down. 

So, what’s Mr Musk up to and why?

BMI, or body mass index, has long been used as a simple calculation to determine if someone is underweight, a ‘healthy’ weight or obese.

But when it was devised by a Belgian mathematician almost 200 years ago, it was never supposed to be a tool to measure health.

Now, researchers are challenging the way obesity is defined and diagnosed. Today, a look at the new approach and why there’s a global push away from BMI.
