Losses confirmed by intelligence agencies are recursive. They confirm what Ukraine claims because they are the Ukrainian claims- see also the CSIS numbers Bruce uses; they match the Ukrainian numbers for Russian casualties, they're not CSIS' own ones. They've also made some ludicrous claims like the Ukrainian counter offensive failing due to pro Russian shrubbery. I don't accept it, but I find that estimate to be more likely. That's partly due to the outlandish claims made by the other side for sure; it's certainly more likely than Russian soldiers wearing welding kit to burn off faces in no man's land. By its nature it would be a lower estimate. Thinking of it as being embarrassing to have losses is a bit of a 'western' (in this case comfortable or similar might be more accurate) concept: the whole DPRK shtick is that they're in a life or death struggle with the forces of imperialism. Showing losses actually enhances that narrative and they get to show that they have friends in the struggle too. You might compare it with some of the jihadi groups which are keen to publicise suicide bombers because they believe that they've gone to heaven and will encourage others in the struggle while westerners would decry it and never once think of condoning or celebrating it. Well, unless it's Ukrainian intelligence doing the bombing and the bomber is an innocent Azeri at least. Both those claims are propaganda. One is aimed at you, one isn't.
