In Brazil this week an alternate reality is unfolding: a former president, who allegedly tried to incite an insurrection to overturn an election, is on trial. A verdict is expected this week, and he may go to prison for the rest of his life.

On January 8th 2023, Jair Bolsonaro’s supporters broke into government buildings, demanding to overturn the result of the election Bolsonaro had lost. In the aftermath of those events, Bolsonaro was accused of masterminding a plot for a military coup. He denies these claims and says the charges are politically motivated.

President Trump has called the trial a “witch hunt” and gone to extreme measures to try to influence its outcome. But have his attempts to influence the trial backfired?

We speak with Ione Wells, the BBC’s South America correspondent, who has been reporting from inside the trial.

In 1994, Ukraine surrendered the world's third-largest nuclear arsenal, inherited from the collapsed Soviet Union, in exchange for security assurances from the US, Russia, and the UK.

Ukraine’s denuclearisation is often considered a huge success story in nuclear non-proliferation, but in retrospect, it may have paved the way for Putin's 2022 invasion.

As talk of US-European security guarantees for Ukraine resurfaces in the context of tentative Russia-Ukraine peace talks, we speak with BBC Paris correspondent Andrew Harding about the history of the 1994 agreement, and consider whether Ukraine would ever again believe promises made to protect it.

President Xi Jinping said humanity faces "a choice between peace and war” as China paraded a huge arsenal of weapons – including nuclear missiles – in Beijing yesterday. Xi's military parade, watched over by Vladimir Putin and Kim Jong Un, seemed a provocation to the west – most notably, Donald Trump – and a signal of his will to redraw the world order, lessening China’s reliance on the US. In today's episode, the BBC's Celia Hatton considers: how long will China's friendships last with world leaders who have for years been its rivals?
