On 7 October 2023 Hamas launched a large-scale attack from Gaza into southern Israel, killing approximately 1,200 people and taking roughly 250 hostage. Hamas publicly claimed responsibility. Three distinct conspiracy sub-claims have circulated: (1) Israel had advance warning and deliberately allowed the attack; (2) Israeli casualty figures were fabricated or exaggerated; (3) Israel staged or orchestrated the attack. The first reflects documented intelligence failures with an unverified "deliberate stand-down" extrapolation. The second is contradicted by forensic documentation from multiple international teams. The third is directly contradicted by Hamas's own public claims of responsibility and captured combatant evidence.
