Parting "Gift".

That's why they needed "North Korean troops" BS. Totally expected. 

President Joe Biden has reportedly approved Ukraine’s first use of US-provided long-range missiles for strikes deep within Russia, the New York Times (NYT) has claimed, citing anonymous American officials. Authorization to use the Army Tactical Missile Systems (ATACMS) was reportedly prompted by Russia’s alleged move to utilize North Korean troops in the conflict, the outlet said. "Russian and North Korean forces operating in Kursk Region" of western Russia are apparently the intended targets for the weapons, the officials told NYT. Russia has neither confirmed nor denied the presence of North Korean troops on its soil, saying merely that its cooperation with Pyongyang proceeds according to a defense partnership treaty.

Keep in mind, this is NYT--they lie for living, but if true--makes no difference militarily. Merely shows impotent rage of Washington and its "parting gift" to Trump, trying to elicit some kind of response from Russia. Well, that means only one thing--404 will lose much more territory, while petulant children from Washington better go back to kindergarten and learn to read properly before trying to play big military games. Cowards, hiding behind backs of proxies.
