Chapter 19

Gaza is sealed off and war becomes cyclical

After Hamas took control of Gaza, Israel imposed a land, sea and air blockade, and Egypt tightly restricted its crossing. Israel said the restrictions were necessary to prevent weapons reaching Hamas. The blockade also constrained civilian movement, trade, construction, medical travel and the wider economy.

The war transforms Gaza

Israel said its objectives were to destroy Hamas’s military and governing capacity and return the hostages. It launched a large air campaign, imposed what its defence minister called a complete siege, ordered mass evacuations and sent ground forces into Gaza. The campaign killed tens of thousands of Palestinians, displaced almost the entire population and damaged or destroyed homes, hospitals, schools, universities, water systems, roads, farms, religious sites and cultural property.

A ceasefire stops the main war, not the conflict

A US-brokered ceasefire took effect on 10 October 2025. The remaining 20 living Israeli hostages were released, Palestinian prisoners were freed, and Israeli forces withdrew to an agreed line inside Gaza. Full-scale warfare receded, but the agreement left the hardest political questions unsettled.
