Russia's setbacks in Ukraine are posing a new set of challenges for Vladimir Putin, who has an overwhelming arms advantage but is lacking feet on the ground to make it count. Not only that, but the Russian President is struggling to motivate the populace as he prepares for "a prolonged conflict" in Ukraine. However, Putin may still have a few tricks up his sleeve on and off the battlefield, especially if the conflict stretches into the Autumn months. Dr Jack Watling is Research Fellow for Land Warfare at the Royal United Services Institute (RUSI), a British defence and security think tank. He joins the show to discuss the situation in Ukraine and when, not if, a larger Russian mobilisation could take place.
