Aharon Haliva is a retired Israeli Major General (Aluf) and former military intelligence officer in the Israel Defense Forces (IDF), best known for his tenure as head of the Military Intelligence Directorate (Aman) from 2018 (or 2021, according to some sources) until his resignation on April 22, 2024. His resignation came amid widespread criticism and accountability measures following the intelligence failures that preceded the Hamas-led attack on Israel on October 7, 2023, which resulted in significant casualties and initiated the ongoing Israel-Hamas war. Haliva publicly accepted responsibility for the lapses in military intelligence that failed to anticipate and prevent the assault, marking him as one of several high-ranking IDF officials to step down in its aftermath.

Haliva's extensive military career spanned over four decades, beginning with service in the elite Paratroopers Brigade. He rose through the ranks, commanding the Paratroopers Brigade, the IDF Officers' School, and the 98th Paratroopers Division. In senior staff roles, he served as head of the operations division in the Operations Directorate, head of the Technological and Logistics Directorate, and head of the Operations Directorate itself before assuming command of Aman. His positions reflect a trajectory focused on operational leadership, logistics, and intelligence, contributing to Israel's defense strategy in a volatile region. Throughout his service, Haliva was involved in multiple conflicts, though specific combat details remain classified. During his leadership of Aman, Haliva oversaw critical intelligence operations, including signals intelligence through elite units like Unit 8200, and national intelligence operations.

As a key figure in Israel's security apparatus, Haliva's influence extended to shaping military doctrine and inter-agency intelligence coordination. His resignation highlighted ongoing debates about accountability within the IDF and the Israeli government, with critics accusing intelligence leaders of underestimating threats from Gaza. No criminal charges have been filed against him, but his departure underscores the political and institutional repercussions of the October 7 events.
