That audio call has been criticized for all sorts of problems. The dialect, the audio put together, the vagueness of the discussion, the fact that the two people sound like two neighbours chatting and not two vetted resistance fighters, etc.
Another example is Israel's most recent claim that the hospital (Al Shifa this time) refused to receive fuel. The phone call is only a few seconds long, the word "fuel" is never mentioned in it, and as an Arabic speaker, I recognized immediately that they were arguing about the "amount" and not the fuel itself. Yet the IDF have published this as "evidence" that the hospital is refusing the fuel delivery, allowing more babies to die. I think it's quite laughable. Turned out later that the IDF promised 2k liters, then decided to send only 300 liters, which would have powered the hospital for half an hour.... totally ignoring that the main issue is that people are being sniped inside the hospital itself, and the yard is filling up with dead and decomposing bodies, some shot for simply stepping foot outside.
I've considered writing about this at more length. I think the Israeli propaganda machine has the quality you would expect from a hobbyist, yet with high aspirations.
