I don’t indulge in ad hominem—either the work is honest and accurate or it is not. The people who are interviewed are extremely qualified. I did not spot any lies. If you do, please leave a comment. I’ll happily add a warning to the post about anything that’s verifiably wrong.
As for whether some people behind Hamas are very rich, some Zionists are very rich too. I have the same standards for all rich people: I like honest attempts to tell the truth and I hate any attempt to deceive.
