Two days after the Hamas-led attack on October 7, 2023, Israeli Prime Minister Benjamin Netanyahu vowed to transform the strategic environment of the Middle East. The assault, which resulted in the deaths of approximately 1,200 Israelis and the capture of 251 hostages, as well as the opening of a second front by Hezbollah from Lebanon and threats from Iran-backed groups, exposed significant vulnerabilities in Israel’s security posture.

Prior to the attack, Israel’s defense strategy centered on deterring and containing Iranian-backed proxies without becoming embroiled in prolonged multi-front conflicts. This approach assumed Hamas and other adversaries could be managed through limited military operations and deterrence rather than comprehensive political solutions. The October 7 assault shattered these assumptions, prompting Netanyahu to promise not simply a restoration of the previous status quo but a fundamental shift in Israel’s strategic approach.

Since then, Israel has pursued a more assertive doctrine aimed at dismantling the military capabilities of its adversaries preemptively. In Gaza, Israeli forces have targeted Hamas’s military infrastructure, destroying tunnel networks, command centers, and weapons stockpiles. In Lebanon, Israel has escalated attacks against Hezbollah, including reportedly killing key commanders such as Hassan Nasrallah and carrying out strikes against their military installations. These actions aim to degrade Hezbollah’s operational capacity and disrupt its supply lines.

In 2024, these efforts culminated in a conflict in June characterized by Israeli forces extending their operational reach into Iranian territory, conducting airstrikes on Iranian military, missile, and nuclear-related sites. The campaign was bolstered by coordinated U.S. military strikes against Iranian nuclear facilities, reflecting a deepening strategic partnership between Israel and Washington.

Israel’s military operations have also extended to Houthi-controlled areas in Yemen, targeting ports from which drone and missile attacks against Israeli territory and Red Sea shipping were launched. These actions exemplify a notable expansion in Israel’s regional military reach and power projection capabilities.

The regional landscape has further shifted following the collapse of Syrian President Bashar al-Assad’s regime in late 2024. Israel seized the opportunity to intensify strikes within Syria, targeting missile arsenals, research facilities, military airfields, naval vessels, and chemical weapons stockpiles. Israeli forces advanced beyond long-standing buffer zones into southwestern Syria, establishing positions that undermine Iran’s supply routes to Hezbollah.

Concurrent with military initiatives, Israel has pursued diplomatic openings with Arab states concerned about Iran’s influence, including Saudi Arabia. Normalization efforts with Riyadh remain a key objective, particularly in light of shared concerns over Iran-backed groups such as the Houthis. Coordination through the U.S. Central Command (CENTCOM) framework aims to enhance regional defenses and intelligence-sharing among aligned partners.

Netanyahu has emphasized maintaining forward defense zones in southern Lebanon, Gaza, and the Syrian border areas to prevent adversaries from rebuilding their military capabilities and to provide early warning of potential attacks. Despite international pressure, including from the U.S. Trump administration, Israel has sustained its military presence in these areas, citing security needs.

Looking ahead, Israeli officials stress the importance of translating military gains into sustainable strategic outcomes. This includes preventing the reconstitution of Hamas’s armed wing in Gaza and establishing governance structures that can provide stability. In Lebanon, Israel seeks security arrangements to block Hezbollah’s military resurgence. Meanwhile, containment of Iranian capabilities remains a priority to avoid cyclical escalations of conflict.

Israeli military planners anticipate continued attacks against Iran’s missile and nuclear infrastructure, as well as the ongoing threat posed by Iran’s regional proxies, including the Houthis. The evolving geopolitical landscape demands that Israel consolidate its defense industries and enhance self-reliance, partly in response to previous strains in U.S.-Israel military cooperation.

Netanyahu’s revised security doctrine, marked by expanded operational reach and proactive measures against adversaries, aims to reshape the Middle East’s strategic balance. This approach seeks not only deterrence but also the establishment of a regional framework incorporating Israel and its Arab neighbors, leveraging military strength toward long-term stability.
