The Inquiry

The violent riots on the streets of South Africa in recent weeks have seen foreigners killed, their shops looted and 5,000 left homeless. They are accused of taking jobs from locals in a country where high unemployment is a big concern - and an example of the gaping chasm that remains between rich and poor. So 21 years after Nelson Mandela pledged to liberate all South Africans from the continuing bondage of poverty and deprivation, why is South Africa one of the most unequal societies on the planet?

Last month Nato ran a military exercise involving over 400 people from 16 countries. It was the most advanced ‘live-fire’ cyber-defence exercise ever carried out. The point of it all? To help Nato countries prepare for an all-out cyber attack. The former US Secretary of Defence, Leon Panetta, has said “there's a strong likelihood that the next Pearl Harbor could very well be a cyber attack that cripples our power system or our grid, our security systems, our financial systems, our governmental systems. This is a real possibility in today's world”. But how real is the threat of cyber warfare? Four expert witness help us separate fact from fiction.(Photo:Binary code cyber war.

In 2000 the world committed to reduce child mortality rates by 2015. At the time, there were on average 90 under-five deaths per 1,000 live births globally. Now there are 46. The UN says that means 17,000 fewer children are dying every day. Unicef has described the improvement as “one of the most significant achievements in human history”. But progress has been uneven. We look at one of the unexpected stars of the race to tackle child mortality – Rwanda – which, between 2000 and 2015, achieved the highest average annual reduction in the under-five mortality rate in the world. How did Rwanda do it? And could other nations follow its example?(Photo: Children Smiling Credit: Wlablack / Shutterstock)

In a matter of months rebels have swept through Yemen, capturing the capital, forcing the president into exile and causing hundreds of casualties as a simmering conflict has exploded into war. But the causes are complex and confusing. The Houthi rebels are from Yemen’s north, and are now laying siege to the southern port of Aden. Are these geographical rivalries the key? The Houthi are Shia Muslims, supported by Iran. The rest of Yemen is mostly Sunni Muslim, and Saudi Arabia is leading a bombing campaign against the Houthi forces. So is this a sectarian conflict, or even a regional proxy war? And the Houthis have allied with former President Saleh, against Yemen’s current leader who replaced him in the transition after Yemen’s 2011 revolution. Are the roots of the current conflict in the failure of that revolution to deliver progress? Four expert witnesses help to disentangle this complex web and explain what the conflict in Yemen is really about.(Photo: Houthi supporters demonstrate against recent UNSC sanc

Later this month 190 nations will meet in New York to discuss the nuclear Non-Proliferation Treaty (NPT), 45 years after it came into force. The Treaty prompted several aspiring nuclear-weapon nations to give up trying to get the bomb, but it also committed nuclear-weapon states like Russia and the US to pursue disarmament. Progress has been made. Overall stocks of nuclear warheads have dropped significantly. But is that the whole story? Both the US and Russia have committed huge sums – over a long timescale – to modernise their arsenals. One expert tells The Inquiry that these modernisation programmes amount to a new nuclear arms race - one which is creating a new generation of less powerful but more accurate weapons. Some argue that such ‘tactical’ weapons are more likely to be used. Another expert witness tells us that the failure of nuclear-weapon states to disarm threatens the NPT itself. And we hear disturbing testimony about the nuclear stand-off between India and Pakistan and a terrifying account of a

Ahead of a historic meeting between Cuba’s President Castro and US President Obama, The Inquiry asks if the island nation’s warmer relations with America are a betrayal of its revolutionary past. More than half a century ago, Che Guevara became a global icon after he fought alongside Fidel and Raul Castro to overthrow an American-backed government and put into practice their socialist ideals. Now Raul Castro has made a deal with the Americans and the lifting of the long-standing economic embargo of Cuba is becoming a realistic prospect. We delve into Che Guevara’s past, the changes already happening in Cuba under Raul Castro and the Obama administration’s motives, to answer the question - what would Che say?(Photo: Fidel Castro and Che Guevara in the mid 1950s.

It seems something is missing from newspapers and TV bulletins - climate change. A story which dominated the news five years ago has dropped steadily down the agenda. One study has found coverage has dropped 36% globally in that time. Why? On The Inquiry this week we hear a tale of chronic political fatigue. We ask whether our hunter-gatherer brains simply aren't wired to think long-term. And we find out why climate change has all the hallmarks of a story likely to make newspaper editors groan. It could be – as one of our expert witnesses tells us – time to "change the narrative".(Image: A man places his hand on the parched soil. Credit: Press Association)

Who has authority in Tibet? Many Tibetans revere the Dalai Lama and support his goal of greater autonomy from Beijing. But officials there hold the opposite view. For them, he is a villainous traitor. Both sides agree that the role of Dalai Lama has been filled for centuries through reincarnation. The current one will turn 80 this year and Beijing is keen to control the process of finding his reincarnation. But he has said that the role will one day end. Better to have no Dalai Lama than “a stupid one,” he said. His comments sparked a furious reaction from Beijing this month. So, will the Dalai Lama reincarnate? Guests include a spokesman for His Holiness and a Chinese analyst in Beijing.

Forty-four years after President Nixon declared “war on drugs”, four US states have now agreed to legalise the sale of marijuana and a majority of Americans supports legalisation. Across the world, drug laws are being relaxed, from Uruguay to Portugal to Jamaica to the Czech Republic. Does this global trend mean the war on drugs has been lost? The Inquiry hears from expert witnesses including an ex-president and a former prosecutor who now defends drug traffickers.(Photo: A person rolling a joint of cannabis. Credit: Press Association)

The beheading of 21 Egyptian Christians on a Libyan beach has exposed the lawlessness of the country ruled by Colonel Gaddafi until 2011. The internationally-recognised government is trying, without much success, to run the country from the eastern city of Tobruk. In Tripoli, another body claims to be the legitimate government. But is the real power struggle between the militias associated with each group – and where does the so-called Islamic State fit in? With neighbours near and far getting involved to push their own agendas, we investigates the forces operating in Libya and what they want. (Image: A Libyan man waves his national flag.

The murder and disfigurement of a 20-year-old woman in southern Turkey has prompted nationwide protests. Demonstrators have chanted the victim’s name, Ozgecan Aslan, and claimed that Turkey is becoming increasingly misogynistic. They point to growing reports of violence against women and restricted access to abortion. Hundreds of thousands of women have tweeted #sendeandat – 'tell your story' in Turkish - to share their experiences of abuse. The powerful president, Recep Tayyip Erdoğan, says that violence against women is the “bleeding wound” of Turkey. But he has also said that women are “not equal” to men. So, is it life getting worse for woman in Turkey? Expert witnesses include a leading Turkish feminist and a member of the governing AK party.(Image: People hold posters of Ozgecan Aslan.

More than 3,000 people are estimated to have died in the Mediterranean Sea last year. The Pope has warned that the waters are in danger of becoming "a vast cemetery". So what could European countries do to stop these deaths? The Inquiry hears evidence about the people smugglers described as the most ruthless travel agents on the planet, the Italian Navy rescue mission that’s been dramatically down-sized, and the claims that saving migrants at sea creates a "pull factor".Presenter: Neal Razzell(Image: The coffins of immigrants who died trying to reach the Italian coast arrive from Lampedusa to Porto Empedocle, 11 February 2015.

War in Ukraine and the threat of conflict in the Baltics raise fundamental questions about the West’s military alliance. What is NATO for? And is it up to the job? More countries have been joining the club, but those who foot the bill seem to be becoming less keen to do so. Do would-be aggressors still believe that an attack on one NATO member would be treated as an attack on all? Our witnesses include a former senior commander and the man who, until a few months ago, led the alliance.(Photo: Romanian army soldiers from the guard regiment hold NATO membership countries' flags at NATO flag raising ceremony in Bucharest, 2004.

79-year-old King Salman has taken the Saudi throne, promising security and stability. But what do his past and his first acts as king tell us about how the country might change under his rule and beyond? Our Inquiry hears from a newspaper editor and an ex-spy who have both met him and from Saudis who hope for change.Presenter: Helena MerrimanPhoto: New Saudi King Salman attends a ceremony following the death of the late Saudi King at the Diwan royal palace in Riyadh (Credit: Reuters)

Most of the nearly 300 girls kidnapped from a school in northern Nigeria last year are still missing. Their plight temporarily brought global focus to a hideous insurgency that seems to produce new horrors every day. More than 17,000 people have died and a million have been displaced in the Nigerian army’s six-year fight with Boko Haram. The army has been rocked by mutinies – including in the division created to fight the militants - and soldiers in other parts of the country have been dismissed for refusing orders to fight in the north. Meanwhile, human rights groups say the army can be nearly as brutal to civilians as the militants are. And in a sign of apparent growing impatience, Nigeria's neighbours have begun sending their own armies against Boko Haram. So this week we ask, Is the Nigerian Army Failing? (Photo: Some of the 59 Nigerian soldiers facing trial on charges of mutiny and conspiracy to commit mutiny over claims that they refused to fight Boko Haram militants sit handcuffed on October 15, 2014 i

After the recent high-profile spat with the US over The Interview – a Hollywood film that mocks North Korea’s enigmatic leader – what do we know about his ambitions? Our expert witnesses include the first Western journalist to open an office in Pyongyang, a businessman who trains North Koreans and an admirer of Kim Jong Un who says he will succeed where his father and grandfather failed.(Photo: Kim Jong Un.

The murder of more than 130 students at an Army school in Pakistan last month shocked the world. In the following days, Prime Minister Nawaz Sharif promised a comprehensive campaign to defeat the Taliban. More than 50,000 Pakistanis have died in militant attacks since 9/11. Pakistani presidents and prime ministers have previously vowed to crack down on militants. But the United States and others have said Pakistan has long harboured "snakes in the back yard" – militants who sometimes benefit the state's interests. Prime Minister Sharif says no longer will there be a distinction between "good" and "bad" Taliban. "We have resolved to continue the war against terrorism till the last terrorist is eliminated," he said. Is he right? Will this time be different? As we'll hear, the stakes extend beyond Pakistan's borders. Experts include a man who has negotiated with the Taliban, a historian on the rise of militancy and a retired Pakistani Army brigadier general.(Image: Pakistan's Prime Minister Nawaz Sharif. Credit:

Billions of dollars are pouring into the latest investor craze - artificial intelligence. But serious scientists like Stephen Hawking have warned that full AI could spell the end of the human race. How seriously should we take the warnings that ever-smarter computers could turn on us? Our expert witnesses explain the threat, the opportunities and how we might avoid being turned into paperclips.

On 8 December at a summit in London Britain’s prime minister David Cameron told delegates from 50 countries and 26 tech firms that online child exploitation “existed on an almost industrial scale" around the world. He announced an “unprecedented package of global action” to hunt paedophiles who use the internet. And just weeks before that a committee of British politicians revealed their belief that the intelligence services could have stopped a May 2013 terror attack in London if Facebook had alerted the authorities to an online exchange between one of the attackers and another extremist. In this edition of The Inquiry we ask: Can the internet be policed?Presenter: Jo Fidgen(Photo: Big Data. Credit: Carlos Amarillo)

In November President Obama stepped onto a plush red carpet at the end of a White House corridor. “My fellow Americans,” he said, “tonight I want to talk to you about immigration.” He promised to bring change through executive action. “And to those members of Congress who question my authority to make our immigration system work better,” he said, “or question the wisdom of me acting where Congress has failed, I have one answer - pass a bill.” That was a dig at his Republican opponents who control the House of Representatives. They failed to pass a bill last year to reform immigration. But that night, after Mr Obama finished speaking, the Republican leader in the House had his own harsh words for the president: “That’s just not how our democracy works,” he said, “the president has said before that he’s not king. And he’s not an emperor. But he’s sure acting like one." With Republicans now in control of both the House and the Senate, the risk of continued political paralysis in Washington is very real.
