Why was the October 7, 2023, attack a turning point in the Israeli-Palestinian conflict?

The October 7, 2023, attack is considered a major turning point in the Israeli-Palestinian conflict because it shattered the long-standing assumption that the security threat from Hamas in the Gaza Strip was contained and manageable.12

The assault, which killed approximately 1,200 people, was the deadliest day for Israel since its independence and the deadliest for Jews since the Holocaust. It fundamentally altered the regional landscape in several ways:32

• End of the Status Quo: For years, many Israeli officials believed Hamas was effectively deterred, leading to a policy critics called "money for quiet." The attack proved this assessment catastrophically wrong, exposing deep failures in Israeli intelligence and military readiness.1
• Disruption of Regional Diplomacy: The attack occurred as the United States was brokering a potential normalization agreement between Israel and Saudi Arabia. By forcing the issue of Palestinian self-determination back to the forefront, the attack effectively disrupted these diplomatic efforts, which had increasingly sidelined the Palestinian cause.12
• Escalation of Conflict: The resulting Israel-Hamas War has led to unprecedented destruction in Gaza, with tens of thousands of deaths and widespread humanitarian crisis, marking a new, more intense phase in the decades-long conflict.4
