These are tricky times for Russian President Vladimir Putin. The “special military operation” he launched against Ukraine in 2022, intended to last a few days until a puppet regime in Kyiv could be installed, has now gone on longer than both the Soviet fight against Nazi Germany and all of World War I. His forces have long ceased making significant gains on the battlefield; some data even suggest that Russian forces lost territory in April and May. What gains the Russians have made have come at enormous cost: Last month, Anna Keast-Butler, the director of British intelligence agency GCHQ, cited new intelligence indicating that Russian war deaths had likely reached almost half a million; various Western sources put total Russian casualties at significantly more than 1 million.

In relative terms, the attrition losses are even more staggering. By some accounts, Russia is now incurring eight men killed or seriously wounded for every one lost by Ukraine. With average monthly casualties running at more than 30,000 this year, the Russian army is struggling to replace them with fresh recruits. It is offering sign-up bonuses as high as $80,000, and up to $140,000 in debt relief to encourage more men to enlist.
