Climbing Russian casualties and reports suggesting that Russia is now looking to North Korea to aid its flagging troops raised eyebrows this week as some began to question whether Moscow would drag Pyongyang into its war in Ukraine. Russia expert and former intelligence officer in Russian doctrine and strategy for the Defense Intelligence Agency (DIA), Rebekah Koffler, threw cold water on these claims and said they were "implausible." "The Russian propaganda machine could say that 100,000 North Korean volunteers would fight on behalf of Russia, just to scare the West, but in reality, it’s disinformation," she said in answer to questions from Fox News Digital.
