Earlier this week I pointed to a Ukrainian (South Korean, US) propaganda campaign which claims that thousands of North Korean soldiers will soon fight with on the Russian side against Ukraine:

To have North Koreans fighting in Russia against the Ukrainian incursion in Kursk would make little sense. That incursion is for one already mostly defeated.

Besides that the language and cultural problems would make the integration of such forces into Russian military operations nearly impossible. I am sure that the Russian military would be strongly against it.

Zelenski's claims were amplified through various proxies and media appearances:
…
I regard the whole claim of North Korean troops in Russia as a fake news story and I am sure that most experts will follow me in that judgment.

However, today US media manage to play up the nonsense:

Why North Korea is sending soldiers to the Russian front lines – Washington Post, Oct 15 2024…
I do not believe that any politician or military in the west will believe that nonsense which is again solely sourced to Ukrainian military intelligence claims. But there is clear campaign by the Ukrainian government to make the issue stick.
