This Is Why

You can have sex, learn to drive and join the army – but can’t be trusted to watch YouTube after midnight. Are the government’s latest curbs on teenage social media use practical or performative?
The proposed curfew for 16 and 17-year-olds builds on the outright ban for under-16s due to come into force next spring – but won’t be compulsory.
With the government committed to reducing the general election voting age to 16, are they in danger of sending a mixed message about how much we trust young people.
Why do we allow teenagers to have certain responsibilities but not others? And should parents take more responsibility for preparing their children for adult life?

Rip up the Memorandum of Understanding, the ceasefire is well and truly over. Iran and the United States are once more at war – with oil tankers targeted and the Strait of Hormuz firmly shut.
Donald Trump's response? He insists the US will take control of the disputed waterway and act as a "guardian angel" for all ships passing through.
Originally, he wanted to charge a 20% toll for the privilege, before backtracking on what seemed like an unworkable claim.
But is the US still in danger of being dragged deeper into a long-term conflict with Iran that could have repercussions for the region – and the global economy – for years to come?

From beef over barbed wire to a shared love of Oasis and The Beatles – the relationship between England and Argentina is... complicated.
On the pitch, it’s one of the great footballing rivalries – defined by Diego Maradona’s "Hand of God" and David Beckham’s red card redemption.
Off it, the two countries share a complex history. The dispute over the Falklands remains at the core of the Argentine psyche, but so too does a love of British music, sport and even red post boxes.
Now, the old rivals are set to meet once more for a place in the World Cup final. So why does this fixture feel so different?
Niall Paterson is joined by the writer, broadcaster and author of Angels With Dirty Faces, a history of the Argentinian game, Jonathan Wilson.

Everybody has a bad week from time to time - but for Prince Harry the last few days have been something of a royal disaster.
The King's wayward son lost his High Court battle against the publisher of the Daily Mail before accusing the judge of a "complete and obvious whitewash".
Days earlier Buckingham Palace denied he would be staying there after the duke's team said he was. And as things stand, there will be no meeting with the King before the end of his stay in the UK.
So, what's next for Harry in the rift with his family and his fight with the press?
Niall Paterson is joined by royal commentator Jennie Bond.
