Russia's invasion of Ukraine unleashed a level of suffering that Europe has not seen in decades and presented global leaders with significant multifaceted challenges. The scale of the humanitarian crisis has been immense, with thousands dead and wounded, millions more forcibly displaced, as Ukraine fights for its independence. Western sanctions have halted significant amounts of Russia's international commerce, yet European dependence on Russian energy resources has complicated the multilateral response to the invasion, with soaring energy prices helping to temporarily prop up segments of the Russia economy. New questions have arisen over the durability and legacy of Putin's authoritarian regime. This session will discuss the crises brought about by the invasion, Ukraine's response, the disruption to the energy sector, markets and the global economy, as well as what the invasion could portend for the future of Russia itself.
