This thing with lesbian black basketball player being released, in exchange for the US releasing this Russian arms merchant (held in prison on a conviction)? Was it a one-for-one deal?
NO.
The original intent was that two would be traded....Russia letting the Marine (Whelan) and the black lesbian basketball player go, and the US getting the arms merchant on the plane, and picking up a German-held prisoner (assassin arrested two years ago for a murder in a Berlin city park).
Basically, there was nothing that the US could offer for the German-held prisoner....so that part of the deal fell apart.
Ethical crap? Once you start trading around for people....the whole value-system that you maintain....falls apart.
