Anton Troianovski: is Russia preparing to invade Ukraine?

Tens of thousands of Russian troops have been massing near the Ukrainian border sparking international concern of an impending invasion.

With tensions mounting, US president Joe Biden has lent support to Ukraine and in a two-hour video call earlier this week he reportedly told Russian President Putin that the US and its European allies would “respond with strong economic measures” if Russia invades Ukraine. But will sanctions be enough to deter President Putin?

Anton Troianovski is the Moscow correspondent for The New York Times, and joins the show to discuss.
