You mean after he passed classified information to the French and Germans, was part of a sabotage ring to intentionally slow down soviet production, and tried to purposefully make mistakes in his designs as a form of sabotage? So he was thrown in a gulag(Scary word for prison because no other country has those right?), and forced to continue working with strict oversight so as to make sure he did not try to sabotage the designs again?

I know the lemmy.world user will not see this, but atleast someone else who doesn’t know this context might.
