This is a leader of one group of rebels. Multiple israeli settlers have confirmed that at least one group of Hamas fighters did exactly what this man is suggesting right after the 7 October aftack
Now should be made clear that not all the Hamas fighters are on one line about this, some just want revenge for the opression israel put them through. However since this was a huge undercover operation there is most likely a lot of secrecy going on. Big group discussions about the goal of the operation or even the operation itself were likely not discussed till the last moment and just passed by word of mouth.
