Yesterday, the French government suspended a proposed hike in carbon taxes amid a mounting wave of protests and violence across the country.

The about-face is a major defeat for President Macron, who rode to power 18 months ago on the promise to take on France's sclerotic political and economic institutions.

The extent of the defeat and what the decision means for France and the EU more broadly remains to be seen. Here are the two crucial questions to keep an eye on:

Will the pause appease protesters? The protests have been fueled by a deep resentment with the French political system that goes beyond the narrow issue of higher gasoline prices. They may not be so easily quelled. President Macron, once the leader of his own political insurrection, has become a symbol of the establishment. That's a perception that can't be fixed through a minor change in policy, and protests are set to continue this weekend.

What does it mean France and the EU? Mr. Macron's government now faces its own pocketbook problem–it can no longer count on the $3.3 billion in revenue expected from the tax. That will make it tougher for it to bring its budget in line with EU-mandated rules and could force it to delay changes to the pension and housing systems that would boost the economy and benefit the very middle-class citizens who've taken to the streets. Problems at home could also make it harder for Macron to pursue much-needed reforms to the EU that have so far made little progress.

The bottom line: In the coming days, Macron will portray the protesters as an unruly mob intent on sowing disorder; the protesters will paint him as the enemy of the people. This is only the beginning of pitched battle for France's future.

Is WhatsApp safe?

WhatsApp had a crazy hack! Hackers were able to get on your phone just by calling it. That's been patched but it's a reminder nothing is ever completely safe in 2019.

Why didn't Uber's IPO perform as promised?

Because they're losing tons of money. Because Lyft didn't do that well. Because their expansion into international markets, where they planned to go, has been harder than expected. Tough times at Uber.

Will cutting Huawei off from American technology hurt?

Trick question! Will it hurt Huawei? Yes, definitely. Will it hurt the American companiesthat supply Huawei? Yes definitely. Will it hurt consumers everywhere? Probably. Unless it changes the dynamics of the U.S. - China trade relationship in such a way that helps everybody, which is possible.

Should more cities ban facial recognition technology?

There's a tradeoff between privacy and safety. San Francisco just blocked facial recognition technology to help privacy but I think most cities are going to care more about their police departments being maximally effective and will choose safety.

In recent years, the accelerating cross-border flow of migrants fleeing violence and poverty has remade the politics of Europe and the United States. A startling new study from Stanford University warns that the conflicts we've seen to date may just be the opening act of a much larger and more dangerous drama.

Here's the study's argument in brief:

President Donald Trump again dramatically escalated the stakes in the US-China rivalry on Wednesday with a move that made headlines in the US while landing like a grenade in Beijing.

The US Commerce Department announced yesterday that Huawei, China's leading tech company and already the source of major controversy, has been added to a list that prevents US tech suppliers from selling to Huawei without a license. That's even more important than the executive order, also published yesterday, that bans US telecom companies from using Huawei equipment.

Voters in Australia head to the polls tomorrow to elect a new government. Though few outsiders closely follow politics in this country, this election tells interesting stories about three of the most important issues in today's world: Immigration, climate change, and managing changing relations with China. It's also a country with a steady economy—but lots of political turnover.
