Are there Really North Koreans fighting in Ukraine? Its unlikely and I sure hope NOT!

Lot of rumblings about Korean troops in Russia, problem is no proofs just lots of words and many of those from Zelenski and other worthless sources. I sure hope Putin is not another evil fool and gives communist scum hands on combat training! He should know better - this is WW3 stuff!
We do some modern combat after with good results!
