I don’t think the story about conscripts is accurate. There were some confused conscripts at places, but 95%+ of Russian soldiers are on contract.
They do conscript people from occupied territories now, but that came later. They entered this war with the expectation that their contract soldiers will do the job (in 3 days).
I don’t believe Kim has any Nork soldiers to spare. It’s the same kind of temporary encouragement false statement that Russia made about Syrian or Ethiopian soldiers coming to fight for them. Neither of these turned out to be real.
They’re getting ammo and weapons from North Korea and Iran, but that only shows how weak they are.
The most recent story about N, Korea I saw was they they would send 100,000 laborers to rebuild the Donbass and other sites for Russia.
