Defense Secretary Pete Hegseth and President Trump delivered extraordinary speeches to top military generals this week, declaring a war on the "enemy within" and signaling a radical transformation of the US armed forces.

To decode what it all means, Roland Oliphant speaks with Mark Cancian, senior adviser at the Center for Strategic and International Studies and a former Marine Corps colonel. Are American soldiers lazier than before? Is there any chance the US Navy will start building battleships again? And how significant is Trump's call for cities to be used as "training grounds"?

They also discuss the ongoing redrafting of the National Defense Strategy and what it means for America's allies and enemies.

Today, Israeli Prime Minister Benjamin Netanyahu is meeting with President Donald Trump at the White House to discuss bringing an end to the conflict in Gaza. Last week, he was giving a fiery speech at the UN General Assembly denying the accusation of genocide levelled at Israel following a UN report.

In response to an earlier Battle Lines interview with one of the report's authors, Venetia gets the other side of the argument with Dr. Eran Shamir-Borer, a former head of the International Law Department in the Israel Defense Forces and part of Israel's team at the International Court of Justice defending the country's against a genocide case there. He is now director of the Center for Security and Democracy at the Israel Democracy Institute and shares his legal perspective on why the UN Commission of Inquiry's report was wrong and Israel is not committing genocide in Gaza. Plus he discusses how Hamas' operating tactics makes the Gaza war one of the most morally and legally complex in modern history.

One of the darling's of the global populist movement, former Brazilian President Jair Bolsonaro, has recently been sentenced to over 27 years in prison in his native country. So what does that tell us about the possible fortunes for other political leaders of the same ilk across the globe, and where does the South American country go from here?

Roland hears from the Telegraph's senior foreign correspondent Adrian Blomfield, who has just returned from Brazil, about his meeting with Bolsonaro's wife and the extraordinary phenomenon of one of the world's largest Catholic majority countries being set to become majority Evangelical Christian in the coming years.

Also in the programme, Roland speaks to Moldovan policy analyst Andrei Curăraru about the country's historic parliamentary elections this Sunday, and how Russia is trying to influence the result.
