Russia is losing soldiers in Ukraine at a rate that may be unsustainable, which is bad news for Putin and slightly good news for Ukraine.

• Russia has lost over 350,000 soldiers killed since 2022, more than US deaths in all of World War II.
• For every square kilometer of land Russia takes in Donbass this year, over 300 of its soldiers are killed or badly wounded.
• Drones now cover the front lines so heavily that wounded Russian soldiers cannot be rescued and bleed to death in the field.
• Russia is now losing more soldiers each month than it can recruit, and Putin's popularity has hit a wartime low, making a new draft unlikely.
• Ukraine has pulled ahead in the drone race and built stronger defense lines, but it has its own problem: not enough soldiers to push back.

Outlook: Russia's goal of taking all of Donbass by autumn looks unrealistic, and if the death toll keeps rising, pressure on Putin to end the war will grow.
