Professor Jacques Sapir is a leading expert on the Russian economy, and part of the Institute of Economic War in Paris. In this wide-ranging historical discussion with the Danube Institute's resident economist, Philip Pilkington, he talks through the long view on Russia's strengths and vulnerabilities. From Stalin doing the impossible to repel the German invasion, to the possibility that collapse could have been avoided in the late '80s, through the desolate '90s, into the dynamics of the fortress economy that Vladimir Putin has developed, post-2014.
