Destiny had a "debate" with Finkelstein a few days ago on Lex Friedman where he verbatim repeated every piece of debunked Hasbara available it was quite embarrassing to watch. Example:
When Finkelstein said that the IDF murdered four children on a beach Mr. Boneri said that was a lie and those children were inside a "Hamas compound. A simple Google shows Mr Canoli had no idea what he was talking about
An account of the investigation, posted late on Thursday by military spokesman Lt Col Peter Lerner, said the strike had targeted a “compound” which had been known as belonging to Hamas’s Naval Police and Naval Force (including naval commandos)”.
But journalists who attended the scene in the immediate aftermath of the attack – including a reporter from the Guardian – saw a small and dilapidated fisherman’s hut containing a few tools where the children had been playing hide-and-seek.
The Israeli claims appear at odds in several details with what journalists were able to see at the time.
So the "The IDF investigated themselves and found they have done nothing wrong" is basically every argument for pro-israeli grifters.
