In their press conference here they even mentionned that Georgia committed "war crimes".
I hope for them that they have some proof.
Both spend 5days in Georgia.
Josy Dubié is from "ecolo" (green party), he has a degree as a merchant navy captain and worked a few years as an officer on a merchant ship. He then passed university for a master in journalism and ethnology, and a baccelor in law and phylosophie.
So he does not sound as a complete fool to me.
