IMO Soros is a disgraceful, malicious, self-hating leftwing Jew. I've never believed the stories about Jews who collaborated with the Nazis, but had Soros been around then, no doubt he would have leaped at the chance to do so.
Personally I think Soros has knowingly funded terrorists. I remember that he commented that the "insurgency" in Iraq hadn't had the effect he had hoped for. To me it sounded like the words of a man with something at stake.
