IDF Revises Security Doctrine After October 7 Failures

The Israel Defense Forces (IDF) have significantly revised their security and operational readiness protocols in the three years since the October 7 attacks, according to a report by Ynet. These changes include increased troop numbers and firepower, expanded intelligence capabilities, and enhanced training for surprise assaults. Despite these upgrades, the article notes that the IDF was considered one of the world's strongest militaries before October 7, possessing advanced intelligence, a powerful air force, and modern technology, yet this did not prevent the initial attack or the subsequent collapse of defenses.

An expert cited in the report emphasizes that the army's current key performance indicator is not new units or fortifications, but the ability to detect threats early, rapidly deploy forces, and make swift operational decisions. This capacity will be the ultimate test for the IDF in the face of any future attempts to surprise Israel. These insights form the basis of a new concept being developed by IDF Chief of Staff Lieutenant General Eyal Zamir, aimed at both preventing surprise attacks and ensuring a rapid, effective response.

The previous military model, which relied for decades on deterrence, intelligence, and technological superiority, proved vulnerable on October 7. The failure was attributed not only to a breakdown in deterrence but also to the army's inability to adapt to scenarios beyond pre-planned contingencies. The IDF is now attempting to rectify these past mistakes through exercises simulating non-standard scenarios, reducing reaction times, and preparing preemptive strike plans, though the article cautions that even extensive training cannot guarantee readiness for unforeseen threats.

On various fronts, the IDF is adapting its approaches to local conditions. In Gaza, the army has shifted from border defense to establishing controlled territory, now overseeing approximately 64% of the strip, reinforcing positions, and destroying Hamas's underground infrastructure with the primary goal of preventing the restoration of its military capabilities. In Lebanon, the IDF is building a deep defense, creating a security zone of about 10 kilometers in the south to distance threats from the Israeli border. A similar zone extends up to 15 kilometers into Syria, intended to shorten reaction times and grant the army greater operational freedom. In Judea and Samaria, the IDF has replaced targeted raids with prolonged operations against terrorist infrastructure, increasing its permanent presence in the region. Across all fronts, the army adheres to the principle of proactively identifying threats and neutralizing enemy forces at their concentration points rather than waiting for an attack at the border.

The main lesson from October 7, the article concludes, is the necessity of maintaining flexibility and avoiding reliance on predetermined scenarios. The IDF's success in correcting past errors will ultimately be demonstrated by its ability to repel a surprise attack.
