Withdrawal from Tanf and Buildup in the Gulf: Redefining the U.S. Military Presence in the Middle East

On February 12, 2026, the Pentagon announced the completion of the withdrawal from the Tanf base in southeastern Syria and its handover to Syrian forces, a move described by the U.S. Department of Defense as "strengthening relations with Damascus." At the same time, Gulf bases are witnessing the largest U.S. military buildup since mid-2025, including the deployment of 36 F-15E Strike Eagle aircraft in Jordan, THAAD and Patriot batteries, and the sending of the aircraft carrier USS Abraham Lincoln to the Arabian Sea. This apparent contradiction reveals a deep strategic repositioning: Washington is withdrawing from the periphery to concentrate in the center.

From Tanf to the Gulf: Tactical Withdrawal or Strategic Shift?

The Tanf base, located at the Syrian-Iraqi-Jordanian crossroads, was considered a monitoring point to prevent Iranian-backed militia movements along the route connecting Tehran, Damascus, and Beirut. The U.S. occupation of this base since 2016 cost it about 200 soldiers and significant logistical resources, but it did not effectively prevent any Iranian convoys from passing through alternative routes. Militarily, the presence at Tanf was more symbolic than operational: the small U.S. force lacked the capability to deter Iran without massive air support, which was not available in the context of a gradual withdrawal from the region.

Now, with the handover of the base to Damascus, Washington is betting that the new Syrian regime, after the fall of Bashar al-Assad, will be less dependent on Iran. However, any military officer who has served in the region knows that abandoning a strategic position means granting the adversary freedom of movement, even if the position is symbolic. Iran has already begun to bolster its presence in Deir ez-Zor and Al-Bukamal for weeks, taking advantage of the vacuum created by Washington's gradual withdrawal from eastern Syria.

Buildup in the Gulf: Deterrent Force or Show of Strength?

As Washington withdraws from Syria, it is pouring troops into the Gulf in an unprecedented manner. Since January 16, 2026, U.S. Central Command (CENTCOM) has deployed the following:

• 36 F-15E Strike Eagle aircraft from three squadrons: the 494th Squadron from RAF Lakenheath in the UK, a squadron from Seymour Johnson Air Force Base in North Carolina, and the 391st Squadron from Mountain Home Air Force Base in Idaho, distributed across the Muwaffaq Salti Air Base in Jordan and other bases
• An F-16 Fighting Falcon squadron from Aviano Air Base in Italy
• An A-10 Thunderbolt II squadron from Moody Air Force Base in Georgia
• F-35A aircraft from the Vermont Air National Guard (158th Fighter Wing)
• The USS Abraham Lincoln carrier group in the Arabian Sea, carrying F-35C Lightning II from Marine Fighter Attack Squadron 314 "Black Knights," in addition to F/A-18 Super Hornet and EA-18G Growler aircraft
• THAAD and Patriot batteries in Gulf countries
• KC-135 Stratotanker refueling aircraft and HH-60W Jolly Green II rescue helicopters

This force, estimated at around 40,000-50,000 personnel, represents the largest U.S. air-naval concentration in the Gulf since mid-2025. The Pentagon states that the goal is to "deter Iran," but the timing reveals other motives: nuclear talks with Tehran in Muscat (February 6, 2026) failed, Iranian-backed militias in Yemen and Iraq continue to target shipping in the Red Sea and the Gulf, and Israel is pressuring Washington to take a firmer military stance.

However, practically, this buildup carries significant risks. U.S. bases in Jordan and Iraq are vulnerable to Iranian missile and drone strikes, as occurred in January 2024 when three American soldiers were killed in a drone attack on Tower 22 in Jordan. Deploying dozens of aircraft in fixed bases makes them easy targets for Iran's ballistic missiles, especially if Tehran decides to launch a preemptive strike to deter a U.S.-Israeli attack.

F-15E vs. Iranian Drones: Is This the Best Use of Resources?

On February 3, 2026, an F-35C from the Lincoln carrier intercepted an Iranian Shahed-139 drone near the fleet. This tactical success raises a strategic question: is using a $100 million fighter jet to shoot down a $20,000 drone the best use of resources?

Analysts at Forbes pointed out that F-15E aircraft, with their ability to carry 29,500 pounds of munitions and speeds of up to Mach 2.5, are suitable for deep and precise strikes inside Iran, but they are too costly for daily patrol missions over the Gulf. In contrast, stealthy F-35s are less susceptible to Iranian radars, but they carry less munitions (18,000 pounds) and are slower (Mach 1.6). The optimal solution, from a purely military perspective, would be to deploy American drones like the MQ-9 Reaper to monitor and intercept Iranian aircraft, but Washington prefers to rely on manned aircraft to send a visible deterrent message.

Regional Allies: Between Dependence and Fear of Escalation

Gulf countries, especially Saudi Arabia and the UAE, welcome the U.S. military presence as a guarantee against the Iranian threat, but at the same time, they are concerned about becoming a battlefield. On February 9, 2026, a plan to upgrade Saudi Arabia's F-15 fleet to the F-15EX standard was presented at the World Defense Exhibition in Riyadh, supported by a $3 billion U.S. maintenance package. This investment aims to enhance Saudi air defense, but it does not change the fundamental reality: Riyadh lacks the capability to confront Iran alone and is entirely dependent on the American umbrella.

The UAE, for its part, has taken a more cautious stance. In February 2026, Abu Dhabi publicly refused to allow its territory to be used for attacks against Iran, a clear indication of its desire to avoid escalation. This position reflects a strategic shift in Gulf thinking: reliance on America is necessary, but not at any cost.

Conclusion: A New Positioning That Does Not Resolve Old Contradictions

The U.S. repositioning in 2026 — withdrawal from Syria and buildup in the Gulf — reflects a new military reality: Washington wants to deter Iran without getting embroiled in a long ground war. However, this strategy carries a structural contradiction: how can an adversary be deterred with air power alone, without the political will to use it? Iran knows that America does not want a wide-ranging war in a region rife with conflicts, which diminishes the credibility of the military threat.

For Gulf countries, the message is clear: America is present, but it will not fight your wars. You must build real defensive capabilities — not just purchase billions of dollars in weapons, but invest in training, maintenance, and readiness. Tanf fell because symbolic military presence is not enough to deter a real adversary. The question now is: will the buildup of 36 F-15E aircraft in Jordan be enough to deter Iran, or is it just another show of strength that ends with a gradual withdrawal after months?

History teaches us that military power without the political will to use it becomes merely a logistical burden. Washington is redefining its presence in the Middle East, but it has yet to resolve the fundamental contradiction: how to deter an enemy it fears to confront?
