US Approves $1.96 Billion Arms Sale to Saudi Arabia to Bolster Defense

The U.S. Department of State officially approved a foreign military sale to Saudi Arabia this week, valued at approximately $1.96 billion, aimed at bolstering the nation's defensive capabilities amid escalating regional tensions. The package primarily consists of sophisticated missile systems and related logistical support, designed to assist Saudi Arabia in addressing potential threats from Iran and its proxies, most notably the Houthi movement in Yemen. As the Middle East remains on high alert due to the spillover effects of the war in Gaza, the Biden administration's move is viewed as a diplomatic and military deployment intended to solidify the defensive capabilities of a traditional ally and deter further regional escalation.

Saudi Arabia has long been a key strategic partner for the United States in the Middle East; however, bilateral relations were strained in recent years over human rights concerns and the civil war in Yemen. With the expansion of Iranian influence in the region and frequent Houthi attacks on commercial shipping in the Red Sea, Washington has recalibrated its diplomatic priorities, viewing the support of Saudi Arabia’s autonomous defense mechanisms as crucial to regional stability. Through this arms sale, the State Department is not only fulfilling long-standing security commitments to an ally but also aiming to reduce the burden on U.S. forces to directly commit significant resources and personnel to contain conflicts in the region by enhancing Saudi Arabia’s military deterrence.

Opinions on the arms sale remain sharply divided. Proponents argue that it helps restore the regional balance of power and ensures Saudi Arabia has the necessary defense capabilities to address the persistent challenge of Iranian-supplied drones and ballistic missiles. Conversely, some human rights organizations and members of Congress express concern that the weapons could be used in the conflict within Yemen, potentially exacerbating civilian casualties. The U.S. government has emphasized that the sale is subject to strict end-use monitoring and humanitarian requirements, reflecting an attempt to strike a delicate balance between security commitments and human rights values.

The approval of this sale also reflects the strategic contraction and pivot of the United States in the "post-globalization" era. Washington no longer views direct military intervention as the primary solution, opting instead to strengthen the self-defense capabilities of its allies and construct multilateral security networks through diplomatic channels. While Iran and Saudi Arabia briefly restored diplomatic ties under Chinese mediation, relations have since cooled due to proxy conflicts. The U.S. decision to increase arms sales to the kingdom at this juncture signals a reassessment of Middle Eastern geopolitical structures by Washington, prioritizing the assurance that core allies are not left at a disadvantage against Iranian pressure.

For Taiwan, this issue holds significant reference value. Although the geopolitical environments of Taiwan and Saudi Arabia are distinct, the model of U.S. arms sales and the underlying strategic thinking serve as a point of reference for Taiwan’s national defense policy and diplomacy with the U.S. First, the U.S. practice of linking arms sales to regional security architectures demonstrates that Washington places greater importance on how allies integrate into broader regional defense systems rather than viewing sales as mere commercial transactions. Second, the trend toward "defense autonomy"—where the U.S. bolsters the defensive capabilities of allies to curb the expansion of regional powers—aligns with Taiwan's current strategic focus on promoting defense self-reliance and building asymmetric warfare capabilities. Observing how the U.S. utilizes arms sales to precisely calibrate diplomatic leverage amidst the complex variables of Middle Eastern conflict will help Taiwan understand how Washington employs similar strategic logic to push for the substantial enhancement of defensive capabilities regarding security in the Taiwan Strait.
