I am saying this is likely a msm lie ghost of Kiev type stuff. Just trying to get more money and weapons.
It's very likely real, anything the US scream in the msm usually is but needs serious filtering.
Like it's not ok NK military are in Russia and likely holding joint military training exercises but it's ok for Ukraine conscripts to be sent to Poland, the UK and the USA for training to actively participate in this war.
Or how Chinese parts are used in the drones the US supply Ukraine for the war but Iranian drones or NK shells are reasons to sanction those countries.
How about the French Foreign Legion being deployed to Ukraine 3 months ago, well they were meet with bombs and haven't been heard of since.
Let alone the many foreign mercenaries taking sabbaticals from active military service to fight for Ukraine for the last 2+years, they were paid well, some stayed, lots will never return. Hell, some kiwis were killed there trying to kill Russians.
After all the support the west has pledged to Ukraine never have they tried diplomacy, even when Russia offered. So this is sticking it to western countries and the NK troops will actively participate in Kursk (Russia) to gain valuable experience and strengthen their's and Russia's ties making them more formidable in the face of western attacks.
If it's good for the goose it's good for the gander..
