First, given his wealth, cleverness, and legal staff, Soros isn't going to leave any money trails that lead directly to himself.
Secondly, there have been many stories about Soros himself being an employee/agent for certain European powers that he started working for in his youth in Hungary. This is why Orban government in Hungary is so adamant about banning his influence (Hungary knows the truth).
I agree with you that Soros is just a cutout between the real money men, and the operational people. Just like Osama stood between the terrorists and the very respectable people in Saudi and elsewhere.
