What now, Mr. Guaidó?

GZERO interviews Venezuelan opposition leader Juan Guaidó.

It once seemed so encouraging for Venezuela's political opposition: Millions in the streets. Strong international support. An unpopular autocrat seemingly on the ropes. But what a difference a month can make.

In early March, Juan Guaidó — the man recognized by dozens of countries as Venezuela's interim president — returned home to cheering crowds. He had been abroad for almost two weeks, currying favor with other regional governments, and trying to get much–needed humanitarian aid to his countrymen.

But in the days since then, little has changed. Venezuelan President Nicolás Maduro remains in power, despite having overseen one of the most staggering economic collapses in modern history.

Guaidó's overtures to the military to drop their support for Maduro have had little effect — only an estimated 1,000 soldiers and national police have defected, despite huge protests, growing sanctions pressure, and the whispered threat of US military action. The top brass remains loyal to Maduro.

In fact, after a few weeks of mostly ignoring Mr. Guaidó, Venezuelan authorities have quietly ratcheted up pressure of their own. Earlier this week, in a pre-dawn raid, the intelligence services detained Mr. Guaidó's chief of staff at his home, raising the possibility that the government may be closing in on Mr. Guaidó himself.

With relatively few tangible gains to show recently, what is Guaidós plan? Is he open to US military intervention? What would a realistic transition look like?

He sits down with us to answer these very questions. Watch the interview here.

Internationally, food security is under threat from drought, while agriculture is subject to thin margins and complex global trade. There is also pressure to do more with less to ensure food security for the global population. Because of this, farmers are driven to get the most out of every harvest, even if that short-term focus may have long-term ill effects on the soil and their yield. Farmers in the U.S. are now turning to Ag-Analytics, a leader in AI solutions, to help address these concerns. Sharing Microsoft's goal to help monitor, model and manage Earth's natural resources with cloud and AI, the company brings precision agriculture to fruition in a platform that helps farmers leverage data to make decisions.

As topsy-turvy as global politics has been over the past several years –Brexit, Trump, the rise of anti-establishment leaders in France, the Philippines, Italy, Pakistan, and Brazil, the surge of the European far right and so on – it's all unfolded during a time when the global economy was actually doing pretty well.

So what happens when the inevitable recession hits? Earlier this week, markets suffered their worst day of the year as investors confronted that question.

Germany's economy, the world's fourth-largest, is shrinking. China's factories are churning at their slowest rate in 17 years. The trade fights between the US and China, the US and Europe, and South Korea and Japan involve countries that together account for half the global economy. And worries about a chaotic British exit from the EU aren't helping either.

Even more worrying than these individual trends, through, is that the zero-sum politics driving all this disruption might also make a global economic swoon harder to get out of.

During the last big economic crisis in the wake of the 2008 financial meltdown, the world's major economies were able to compromise and coordinate their responses to the recession in ways that avoided an even deeper downturn.

In today's more cutthroat political environment, that kind of cooperation is a lot less likely -- particularly if a downturn fuels even more of social and political polarization within countries that has empowered economic nationalists in the first place.

We're not in a recession yet. But buckle up, because when the next downturn hits, politics is going to make it harder to contain the pain.

A pivotal weekend in Hong Kong – Some 300,000 demonstrators are expected at Hong Kong's Victoria Park on Sunday, in the 11th straight week of protests. Chaotic and partly violent demonstrations shut down Hong Kong International Airport this week, and tensions are high. Chinese paramilitary forces are reportedly drilling on the mainland close to the Hong Kong border. Xi Jinping, the president of China, knows a military crackdown would cripple Hong Kong's reputation as a stable financial center and could hurt the Chinese economy more broadly. But he may eventually conclude he has little choice but to snuff this out before other restive regions of China get similar ideas. The tenor of the marches this weekend will offer a clue about which way it's likely to go.

Maduro's crackdown on the military – One reason Venezuelan President Nicolas Maduro has survived an economic collapse, a popular revolt, assassination attempts, and a failed coup by opposition leader Juan Guaido is that the military brass has stuck with him. For one thing, they are tied to the regime's lucrative illegal businesses and black market schemes. But there's also now a stick to go along with that carrot: The New York Times describes Maduro's "growing reliance on torture" and purges of military officers – including alleged coup-plotter Captain Rafael Acosta, who died after being beaten and electrocuted to in a Venezuelan military hospital. We are watching closely to see if there is a point where Maduro screws up the calibration of carrots vs sticks and finds himself at the business end of a rifle in the Miraflores palace.

Trudeau's woes – In many ways Nicolas Maduro's polar opposite, Canada's prime minister has a lot going for him: dreamy good looks; a decent – if not overwhelming – majority for his Liberal Party in Parliament; and a generally safe, resource-rich country with millions of lakes, friendly people, big skies and (relatively) small problems. But earlier this week, an independent ethics commissioner ruled that the prime minister had breached the country's conflict of interest laws earlier this year when he pressured prosecutors to ease off of a bribery investigation of a major Canadian construction firm, because of fears about job losses. Trudeau has accepted the report's findings, but isn't resigning. We're watching to see how this simmering scandal affects Canada's upcoming national elections in October.

What We're Ignoring

Japanese robotic tails Researchers at Japan's Keio University have developed a wearable robotic tail that they say could help elderly people and others with balance problems steady themselves. Look, we know that managing an ageing population is one of Japan's most pressing challenges. We also know that automation is one way that countries with shrinking workforces can better support a growing population of retirees. But giving people tails seems like a less efficient way to address these problems than, say, tweaking immigration policy ever so slightly to bring in more young workers, no?
