He wasn't the sort of person you interacted with and fluttered away from; he was the type of man you fell for. People got hurt when they got attached to other people, because people always left or were taken away. Falling in love, therefore, was just a set-up for inevitable failure. She knew all this. But logic is fallacy when it spars with instinct. So she fell anyway.
[T]he useful idiots, the leftists who are idealistically believing in the beauty of the Soviet socialist or Communist or whatever system, when they get disillusioned, they become the worst enemies. That’s why my KGB instructors specifically made the point: never bother with leftists. Forget about these political prostitutes. Aim higher. [...] They serve a purpose only at the stage of destabilization of a nation. For example, your leftists in the United States: all these professors and all these beautiful civil rights defenders. They are instrumental in the process of the subversion only to destabilize a nation. When their job is completed, they are not needed any more. They know too much. Some of them, when they get disillusioned, when they see that Marxist-Leninists come to power—obviously they get offended—they think that they will come to power. That will never happen, of course. They will be lined up against the wall and shot.
