> because their passports are kept away from Western databases. Except unless they get arrested in the West and their secret passports fall into Western intelligence hands. > It doesn’t help to block spy operations, because you can connect passport numbers to specific actions only after they happened But getting caught must be no fun. > It doesn’t help breaking plausible deniability to blame Russian government officially, because you would need the hard evidence.
