Yuval felt a sense of national duty after the attack, which killed 1,200 people and abducted 250. He saw it as an existential moment and wanted to protect Israel from further harm.
Yuval refused an order to blow up a house in Gaza, as he found the reasons given by his commander insufficient and could not justify the destruction without a clear military purpose.
Yuval compared the destruction in Gaza to an apocalypse, describing buildings leveled by fire and missiles, and a chaotic scene of total devastation.
Yuval witnessed soldiers looting and vandalizing Palestinian homes, using derogatory language about Palestinians, and engaging in acts of disrespect, such as dressing in stolen women's clothes.
