It is rumoured that Russia's leader will assess whether to attempt another offensive in March. No large city has fallen since Mariupol in May 2022. The towns that have, such as Avdiivka and Bakhmut, were reduced to rubble long before the Russian flag was raised.

How Russia’s fatalities compare with Ukraine’s After four years of fighting, our modelling reveals a grim toll

The latest casualty estimates—from official and independent sources, as well as The Economist’s own modelling—suggest that Russia is losing far more troops than Ukraine, while gaining almost no ground. www.economist.com/graphic-deta...

Seven conflicts to watch in the coming year Some are potential, others are already hot

Every November, @economist.com ponders the year to come. For this year’s edition of The World Ahead, I wrote about the conflicts to watch in 2026. I highlighted seven—of which one has already taken a major turn. www.economist.com/interactive/...

Russia's latest big Ukraine offensive gains next to nothing, again Hundreds of thousands of Vladimir Putin's troops are losing their lives for barely any land

Russia does not appear to be winning the war on the battlefield. It is advancing only slowly, with little hope of a breakthrough and at a cost that is unsustainable in manpower and materiel. My latest on the war: www.economist.com/interactive/...

Lack of enough data precludes doing the same for Ukraine. But we do find that while Russian forward movement is still slow, it is speeding up. More at link: www.economist.com/interactive/...

To estimate Russian losses, I lined up satellite data and shifts to areas of control in Ukraine with more than 200 estimates of total casualties there. This enabled me to construct a credible day-to-day range for the toll of the war since the invasion.

How often do ceasefires in the Middle East work? Donald Trump says he expects the Iran-Israel truce to last forever. Our analysis of more than 2,000 truces suggests that’s optimistic

Whether a specific ceasefire will hold can be very hard to tell. But data on masses of them, researchers told me, reveal some factors that tend to be correlated with success. I had a look at 2,203 declared since 1989: www.economist.com/graphic-deta...

Mapping the Ukraine war: where is the latest fighting? Our daily updated satellite view of the conflict

Just saw this. It would be possible to replicate the approach if I knew the locations of strategic sites to monitor within Israel. It is also possible to do this independently of strategic sites, as I do in Ukraine. www.economist.com/interactive/...

While tracking thermal events is not perfect either, it has some advantages: it covers all sites systematically, and data comes in regardless of access (as long as skies are clear), several times daily.

To track the Israel-Iran war, @economist.com, I think uniquely, monitors 208 strategic sites in Iran for abnormal thermal activity. It can be hard to know how much maps of confirmed strikes may miss. We find broad overlap, but not perfect. www.economist.com/interactive/...

Russia has attacked along virtually the entire front in the past week, and especially heavily in the past few days. But essentially no shift in the front lines. www.economist.com/interactive/...

Is Zelensky a disliked dictator or a popular hero? Our poll of Ukrainians shows a surprising shift in the president’s ratings

Our poll of Ukraine is now in (N=1000). Mr Zelensky approval at >70%, very few want elections before peace. But also suggests 58% will not want Ukraine to concede territory, and that many also expect the war to end within the year ->

What Ukraine’s bloody battlefield is teaching medics Western armies have not dealt with mass casualties since the 1950s

Some sources provide casualties (dead+wounded), some provide dead only. I collected both. More on dead-to-wounded ratios here: www.economist.com/internationa...

I cover both casualties (dead and wounded) and dead. The chart that appears with the link shows fatalities only. As you may know, this cuts both ways: a lower dead-to-wounded ratio means that for any given set of fatalities, there are more wounded and thus probably more soldiers out of action.

How do Ukrainian soldier fatalities compare with Russia’s? Russia is losing more troops than its opponent. That makes it a strange time for America to force an unequal peace on Ukraine

In 2024, Russia seized less than half a percent of Ukrainian land at the cost of about 100,000 lives, new estimates of casualties and my calculations suggest. My take on the latest data:

Which goods are most vulnerable to American tariffs on China? Our number-crunching shows which trade flows could be hard to replace

The impact of the latest round of tariffs on US imports from China depends on what the alternatives are. If you thought most of these imported goods are easy to get from elsewhere, I'd think again

What makes ceasefires, such as the one between Israel and Hamas, more likely to succeed? The experts I talked to and data from 2000+ recent halts in fighting suggest monitoring, politics and a strong start are key:
