@zebuceta I'm sure they used his jewishness to get them to turn, perhaps bringing up Russia's cozying up to Iran as proof that Russia is a threat to the Jewish people, thus giving him more incentive to betray his country.
However, in the end, mercenaries are gonna do what mercenaries do. Relying on mercenaries in a war against NATO, which (currently) controls the world's monetary system, was always going to temp your mercenaries to betray you.
