On 9 May, the day the Red Square parade took place in Moscow, US President Joseph Biden signed the Lend-Lease Act for Ukraine. This is the second law of this kind in history — the first one was passed during WWII. What does it mean for Ukraine, how important and timely is the law, does it imply an imminent transition to a new phase of the war, did this decision take Moscow by surprise, and should we still expect a general mobilisation in Russia? We will discuss these and other questions with military experts Oleksiy Melnyk, Co-director of Foreign Relations and International Security Programmes at the Razumkov Centre, and Yuriy Fedorov, an independent political-military analyst.
