What it ISN'T: "Hey, we've got this high-profile arms dealer of yours who's never going to see the light of day again. We'll trade him to you for Griner."
What it IS: "We have an arms dealer of yours. He's been in prison since 2008 on a 25 year sentence. All of his contacts have long since been burned and you can't find armaments anyway. We'll release him 10 years early in exchange for Griner."
