To the west, strikes near Poland have rattled NATO partners. But look to the south-east to see what Russia intends for the Ukrainian cities it encircles. Chile’s new president Gabriel Boric is just the latest leftist to take office in the region; we examine the “pink tide” that is coming in. And why British retail workers are sporting body cameras.

We tackle some of the many questions on the war in Ukraine that listeners sent in this week—why no-fly zones are a perilous idea, how weapons are making their way into Ukraine, why mud is a growing tactical concern, the implications of oil-and-gas embargoes and much more. For full access to print, digital and audio editions of The Economist, subscribe here www.economist.com/intelligenceoffer
