U.S. Middle East Security Policy After October 7

The October 7 attack overturned many of the Biden administration's assumptions about the Middle East and forced Washington to adapt to a fast-moving regional crisis. This essay argues that the administration achieved some limited security aims, but broadly failed to meet its wider objectives.

The analysis uses a chain-reaction framework because developments after October 7 were deeply interconnected. It examines the administration's response under six aims: defending Israel and restoring deterrence, preventing regional escalation, safeguarding U.S. personnel, stabilizing the region, mitigating civilian disaster, and protecting critical shipping lanes.

Before October 7, the United States was already in a difficult regional position. It was trying to reduce its military footprint, manage stalled Iran nuclear diplomacy, respond to China-brokered Iran-Saudi normalization, and pursue a potential Saudi-Israel normalization deal.

The first aim was to defend Israel and restore deterrence after Hamas's attack and the hostage crisis. Washington responded with extensive military aid, naval deployments, air-defence support, and diplomatic backing in international forums.

This support helped Israel rebuild a degree of deterrence and defend against major Iranian missile and drone attacks. However, diplomatic protection also carried reputational costs as global criticism of Israel's conduct in Gaza intensified.

The second aim was to prevent regional escalation. Secretary of State Antony Blinken's regional diplomacy and backchannel warnings to Iran sought to keep the war contained, but cross-border fighting with Hezbollah intensified and Israel eventually expanded military action beyond Gaza.

The conflict widened through proxy activity in Yemen, Iraq, Syria, and Lebanon, as well as strikes involving Iran and Israel. In this respect, the administration failed to stop a limited Gaza war from becoming a broader regional security crisis.

The third aim was to safeguard U.S. personnel. The administration launched retaliatory strikes against Iranian-linked militia targets, and proxy attacks later slowed. Yet the high number of attacks on U.S. bases, injuries to service members, and deaths of U.S. soldiers showed that personnel protection was only partially successful.

The fourth aim was regional stabilization. Efforts to secure a Gaza ceasefire, revive the Iran nuclear track, and advance Saudi-Israel normalization all stalled or failed. The fall of Assad and the rise of HTS in Syria also raised questions about long-term regional order.

The fifth aim was mitigating civilian disaster. The administration pressured Israel on humanitarian access, supported airdrops, and built a temporary pier off Gaza, but these efforts had limited practical effect and did not prevent severe humanitarian deterioration.

The sixth aim was protecting shipping lanes. Houthi attacks in the Red Sea disrupted global trade and reduced traffic through the Suez Canal and Bab el-Mandeb. Operation Prosperity Guardian and sanctions reduced but did not end the threat.

Overall, only two of the six aims saw limited, conditional success. The administration left behind a more fragmented and militarized regional environment, demonstrating the gap between U.S. strategic intentions and regional leverage after October 7.
