The Kerch bridge, a vital supply route for Russian forces in Crimea, has been partially destroyed in a huge blast. It was a symbol of Russia’s annexation of Crimea from Ukraine, and the explosion was equally symbolic, coming just one day after President Putin’s 70th birthday. The Russian president described it as “an act of terrorism”, and he punished Ukraine’s cities with a day of missile strikes, targeting civilian areas. All this comes as Putin’s Special Military Operation is struggling. Ukraine has now seized back more territory than Russia took in the early stages of the war. Hundreds of thousands of Russian army reservists have fled rather than being sent to the front, war deaths and the financial costs of the war are mounting, and winter is approaching. But for President Putin, there is no easy exit from Ukraine. He may have no political choice but to double down, and has even dropped dark hints about using nuclear weapons. So this week on the Inquiry we ask: Is Putin’s war in Ukraine at a turning point?
