Inspired by Viktor Bout who committed the unforgiveable crime of doing exactly what the US and UK do, shovel weapons all over the place with both hands, but he just sold them to the wrong side, i.e. the ones fighting the American proxies.

He's been offered in prisoner exchanges, most recently for the basketball player Griner in Russia. Even Wiki has to detail the political prisoner allegations:
