I still don't get why Russia is not just putting him on military transport to Cuba. They should have "some" experience flying that route without US interference. Nobody would mess around with a military transport and getting him out of the country would probably reflect on Russia better than just harboring him around at the transit zone.
> just harboring him around at the transit zone. Russia are not harboring him because he's not in Russia, he's in an international transit lounge and therefore not actually in any country. It has always shocked me that US airports don't have this concept, it must be the only major world transport hub that doesn't.
So what happens if you commit a major crime in that area? Who responds to a terrorist event there?
I don't know specific international laws, but I would guess that Russia has such an area for her own convenience (that if you are just passing through there's no need to bother with forcing you through Russian customs). But I would guess that Russia has every ability (and every legal right) to do whatever they want in that area whenever they want to, but is choosing not to on its own accord.
