Iranian Military Strikes U.S. Base in Bahrain, Raising Regional Tensions

The Iranian military recently announced that it has launched a drone strike against the Sakhir Air Base in Bahrain. According to a statement released by the Iranian military, the operation constitutes the 11th phase of a military campaign codenamed "Saegheh" (Lightning). Given that Sakhir Air Base is a highly sensitive strategic facility that has long served as a storage site for U.S. military helicopter fleets and P-8 maritime patrol and reconnaissance aircraft, this attack marks a direct military action by Iran against U.S. deployments in the Middle East, a move that is expected to further escalate regional tensions.

The Islamic Republic of Iran Army (Artesh), as the country's conventional military force, stands alongside the politically influential Islamic Revolutionary Guard Corps (IRGC) as one of the two pillars of Iran's national security. While their responsibilities in maintaining national security and territorial integrity overlap, the two have long engaged in intense competition for resources and influence. Analysts point out that this "Saegheh" operation was carried out by the conventional military rather than the IRGC or its proxy organizations—a development suggesting that the Iranian military is seeking to assert greater influence within the domestic decision-making hierarchy by demonstrating its long-range strike capabilities and its ability to conduct precision strikes across borders.

The target, Bahrain, has long served as the home of the U.S. Navy’s Fifth Fleet and functions as a critical military logistics hub for the United States in the Middle East. The P-8 reconnaissance aircraft stationed at Sakhir Air Base are primarily responsible for monitoring activities in the Persian Gulf and the Arabian Sea, representing a core threat to Iran by tracking its maritime operations and oil export routes. By utilizing drones for this surprise attack, Iran has not only issued a direct provocation against U.S. facilities but has also sent a strong geopolitical signal to the U.S. and its regional allies, aiming to disrupt American intelligence gathering and military deterrence capabilities in the Persian Gulf.

Observers believe that as the "Saegheh" operation reaches its 11th phase, Iran is gradually testing the response capabilities and limitations of air defense systems throughout the Middle East. While Iran has historically relied on "gray zone" tactics through proxies such as Hezbollah in Lebanon and the Houthis in Yemen, this direct strike by the conventional military indicates that Tehran is no longer ruling out direct military confrontation in the face of U.S. encirclement in the region. This move challenges the regional military balance and leaves neighboring countries, such as Bahrain and Saudi Arabia, facing heightened security uncertainty, placing the fragile power structure of the Middle East under severe strain.

For Taiwan, although this incident occurred in the distant Middle East, the underlying "drone tactics" and the use of a conventional military for precision strikes against foreign military bases offer significant implications for Taiwan’s defense strategy. Faced with the long-term military threat posed by the People's Liberation Army, strengthening detection and countermeasures against low-altitude, small-scale drone attacks has become an urgent priority for Taiwan's national defense. Furthermore, instability in the Middle East frequently impacts the stability of global energy supply chains. As a nation highly dependent on energy imports, Taiwan must remain vigilant regarding the ripple effects of such conflicts on international oil prices and maritime shipping lanes, while continuously strengthening energy resilience and strategic stockpiles to mitigate potential supply chain disruptions.
