Well the FSB ain't what it used to be
Once upon a time, the KGB would have first gotten dirt on the prospect, or fabricated it if there was none to be had. Then there would have been a night out, but with girls, not friends, and the deal would have been proposed. Of course, the dirt would have been hinted at, then blatantly exposed if the prospect was not compliant. When the deal had been agreed on, the prospect, now very willing accomplice, would have remained under surveillance until completion of the mission.
Don't they watch The Americans any more ?
Pff. Amateurs.
