An investigation by The New York Times has revealed significant changes in Israel's military operations following the Oct. 7 Hamas attacks, including expanded target selection and modified risk assessment protocols.
According to the investigation, the IDF issued an order at 1 p.m. on Oct. 7, 2023, that gave mid-ranking officers expanded authority to strike Hamas targets. The change came in direct response to the morning's attacks, which killed 1,200 people and saw approximately 250 others taken hostage by the terror group.
The New York Times reported that Israel increased its target range while adjusting civilian risk parameters, leading to approximately 30,000 munitions being fired into Gaza in the war's first seven weeks – surpassing the total used in the following eight months combined.

The report indicated that after depleting its pre-existing database of vetted targets, the IDF switched to a new artificial intelligence system for identifying targets. Instead of using detailed surveillance methods employed in previous campaigns, the military began relying on statistical models based on cellphone usage patterns to assess civilian presence.
According to The New York Times, the IDF raised its civilian casualty risk threshold from previous limits of zero to five casualties to a new standard allowing up to 20 civilian casualties per strike. However, the report indicated that senior commanders occasionally approved strikes on Hamas leaders knowing they could endanger more than 100 civilians. Additionally, the military reduced its use of warning shots, known as "roof knocks," that traditionally gave civilians time to evacuate.
The IDF responded that its forces continue to operate within legal parameters, emphasizing that the changes were necessary due to the unprecedented nature of the conflict and Hamas's tactics of operating within civilian areas.
