You're kinda wrong. Yuri want to lure the Soviets to prevent from attacking the Mental Omega Device in case the Allied Forces failed to do so, as he know by the time the Allies failed to win he won't had much time to recover as the Soviets will just clean the rest of the Epsilon in Antarctica. Hence he applied to the use of RUSE.
The title of the final Soviet Mission is something I don't want to interpret at the moment, who knows what it was.
I'm aware, that Yuri just wanted to drag the Soviets to Moscow to distract them from Antarctica, but my point was, that he doesn't really care about destroying enemy armies. Probably, this wasn't even his real plan all along. The Epsilon is on the run all over the planet, just like the Brotherhood of Nod in TW, according to Kane's plan. BTW, the "Death's Hand" is mentioned in debriefing of "Conqueror", perhaps its construction was the reason to start the entire war.(obtaining the Topols) But who knows, what it is?
