Japan is a pacifist country - at least that is what its constitution says. The wording, introduced under the occupying forces after World War Two, seems unequivocal: “the Japanese people forever renounce war as a sovereign right of the nation”. But new laws championed by conservative prime minister Shinzo Abe introduce a broader interpretation of what the constitution does, and does not, permit. Abe calls it “proactive pacifism”. Opponents say the laws are “war bills”, betraying the pacifism that has, for many, become central to Japanese national identity. There have been dramatic scenes in parliament with opposition MPs in tears. The majority of the public are opposed and people have taken to the streets in their tens of thousands. So is Japan abandoning pacifism? (Photo: Sumiteru Taniguchi. Credit: AP)

Tens of thousands of people have marched in Buenos Aires and elsewhere in outrage at the astonishing frequency with which women are being killed in Argentina - the vast majority at the hands of their partners or former partners. Violence directed at women and girls is at the extreme end of the scale. But the protesters believe it grows out of the 'machista' culture - where men have to be macho, and women have to do as they are told. In many ways, Argentina is not a special case - we could, perhaps, ask the same question of many nations. But this week The Inquiry is focusing on Argentina because the protests started an urgent debate inside the country about why women are seen as disposable. And, also because the most powerful office in the land is held by a woman - Cristina Fernandez de Kirchner - twice elected president. Why is this power not trickling down? Why is Argentina still so sexist?(Photo: Argentina Femicide Demo. Credit: Getty Images)

The UN forecasts that the number of people living in Africa will double in the next 35 years. Nigeria, the fastest-growing nation, is expected to become the third largest country in the world by 2050. By the end of the century, almost 40% of the world’s population will live on this one continent. It raises questions about how countries – some of which are already facing big challenges – will cope with twice the number of inhabitants in just one generation. There are fears about the impact a demographic explosion will have on health, society and the environment. But others say Africa’s population boom could turn out to be a good news story. Ruth Alexander asks - how will a population boom change Africa?(Photo: Onitsha-Asaba Highway. Credit: Pius Utomi Ekpei/Getty Images)

In 2011, following a devastating tsunami, Japan’s Fukushima nuclear power station went into meltdown, leaking radiation. It was the most serious nuclear accident since Chernobyl. It appeared to send the nuclear power industry into retreat – and not just in Japan. Other nations had second thoughts too. Germany decided to phase out its nuclear reactors altogether. But now Japan has resumed nuclear power generation. At the heart of the 'nuclear wobble' of 2011 is the question of risk. Attitudes to, and understanding of, risk vary surprisingly between nations and cultures. But after one of the most shocking incidents in nuclear power's history, will we be able to cope with our fears? In other words, can we learn to live with nuclear power? (Photo: A Czech Power plant.

Tens of thousands of migrants continue to queue at the borders of the European Union in search of a better life. Their journeys are often hazardous and thousands have drowned in the Mediterranean trying to reach Italy or Greece. Attempts to share the burden among EU member states have been dogged by internal politics. And Europe’s actions so far have focussed on deterrence despite little evidence that such a strategy will work. So, in this week’s Inquiry, we’re asking what else Europe could try – and whether there are examples from other places, and other times, from which the EU’s leaders could learn. We look at the 1980s resettlement process in response to the Vietnamese “boat people” crisis; we examine Australia’s offshore processing of migrants; and we ask whether focussing on the “front line”, helping those countries migrants are leaving, is a realistic option.Presenter: Ruth Alexander(Photo: Young migrant at Psalidi on Kos, Credit: Press Association Wires)

Robots are coming for your job. Blue-collar jobs in industries like manufacturing have been disappearing for years but now white-collar work is under threat too. Machines are already taking roles that used to be done by journalists, lawyers and even anaesthetists. One recent study calculated that 47% of total employment in the US is at risk of automation in the next 20 years.So what will happen to all the human beings who did those jobs? Will we invent enough new jobs to keep them occupied? If not, how will they fill their time? And how will they earn money? The Inquiry – still made by humans, for now, – brings you answers.(Photo: A robot stands with workers at a Japanese employee supply company. Credit: Getty Images)

In June last year the world's attention became fixed on the progress of so-called Islamic State, or IS. They had just captured Mosul, Iraq's second-largest city. Since then a reported 20,000 fighters from all over the world have joined them. They have killed and enslaved thousands. They have captured towns, oil fields and dams. They control vast swathes of Iraq and Syria. IS are more brutal, sophisticated and enduring than anyone could have predicted. We test the argument that stopping IS will ultimately mean talking to them.(Photo: ISIS Propaganda image)

This July, it was reported that a woman from Washington State in the US had died of measles. It was the first measles death in the country in 12 years and comes after a huge spike in the number of cases of the disease. There is little doubt about what has caused the rise. The 'anti-vax' movement – activists who refuse vaccines believing them to be harmful to children – is vocal, vibrant and virulent. But with their claims proven time and again to be without any scientific basis, why are the 'anti-vaxxers' still going – and apparently growing?(Photo: Measles Cell. Credit: Shutterstock)

In 2009, UK Prime Minister Gordon Brown declared “the beginning of the end” for off-shore tax havens. Since then, the EU, the G20, President Obama and others have lined up to criticise them. And yet they arre still with us. Tim Whewell asks why tax havens continue to exist, and whether tax havens are really to blame for tax avoidance in the first place.(Photo: Island in the Seychelles.

China's economy was up 150% until June. Then it fell by nearly a third. Now it has had the strongest two-day rise since the 2008 global crisis. China’s rollercoaster stock market has provoked panic in recent weeks; panic on the part of small investors, who looked on in horror as previous gains were wiped out, and panic – some would argue – on the part of the Chinese government, which did everything it could to stop the slide. Four expert witnesses analyse what these dramatic events tell us – not about the Chinese stock market, but about China itself.(Photo: An Investor walks past a stocks and shares board.
