The Soviets would have SPOKEN UP if it was a problem as they knew that our side had ADULTS running it. So, like I say, whatever was going on didn’t bother the Soviets.
The Soviets were playing the same spy game as everyone else. They knew the Finns didnt really have their backs, the opposite was the case, but they really didnt want the mess of trying to take over and rule them directly. So both sides played pretend.
Something similar went on with “neutral” Austria.
