I guess that is true IF the following is true:
>“Russian military losses, of those killed and wounded, now exceed sustainable recruitment and replacement rates,” James Ford, Britain’s deputy ambassador to the Organization for Security and Cooperation in Europe said in a speech last week.
The well of humanity can't be bottomless, but I swear I've heard this sentiment years earlier in the war too. They're still fighting and throwing handfuls of troops at the front lines, seemingly carelessly.
Historically speaking Russian leadership's willingness to take massive casualties of their own with little if any political fallout has proven effective, sadly. Maybe WE can't imagine taking losses like this, but in Russia they seem more than willing.
