As Ukraine seemingly makes dramatic advances on the battlefield, we look at what this may say about the situation inside Russia itself. Military analysts are describing what seems to be a depleted Russian military machine, lacking in morale, but also possibly lacking in the kinds of military equipment it needs to sustain its war effort. One estimate in August put the loss of hardware (not including missiles) at $16 billion. That's hard to replace, given the supply problems and falling growth brought about by wide-ranging western economic sanctions. We look inside the country at the way the economy is progressing, with the thoughts of one Russian business-owner, Dmitry Nechaev, and from western-based economists, Sergei Guriev at Sciences Po University in Paris, and Elina Ribakova, deputy chief economist at the International Institute of Finance. The US-based political scientist Stephen Crowley, of Oberlin College, then considers how much a weakened economy is likely to create the type of political pressure to make President Putin reassess his war strategy.
