[spoiler]So, basically, they give up the American dream and way of life to go back to the stinky Soviet Union where they'll probably either be killed or wind up working in a mule glue factory and only able to buy bread once a week if they're lucky. As far as any intelligence agency is concerned, they are nothing but washed up failures. If it had been me, I would have defected and gotten into the witness protection program. Sure, I may be tracked down and killed, but at least in the meantime, my life would be better than that of being in the USSR.[/spoiler]
