In a virtual summit, US President Joe Biden voiced deep concern over Russia's build-up of forces near Ukraine, while his Russian counterpart Vladimir Putin demanded legally-binding security guarantees that would rule out Ukraine ever joining the NATO military alliance. Edward Fishman from the Atlantic Council's Eurasia Center in Washington explains what kind of economic sanctions the US has at its disposal to deter Russia. Also in the programme, Lucas Chancel, Codirector and Senior economist at the World Inequality Lab, explains how the world became more unequal during the Covid-19 pandemic. And the boss of a US company has fired 900 members of staff on a single Zoom call. Was this a violation of basic firing etiquette, or a quicker way to finish an unpleasant experience for all involved? We discuss that, and all our other stories, with our contributors Stefanie Yuen Thio in Singapore and Mitchell Hartman in Portland, Oregon. (Image: Vladimir Putin speaks to Joe Biden via video link.
