Pentagon Considers Major Shake-Up of US Military Force Posture in Europe and the Middle East

The Pentagon is evaluating significant adjustments to how it positions its forces in Europe and the Middle East, potentially leading to a major military restructuring. The administration of President Donald Trump emphasized in this year's National Defence Strategy a desire for allies to take on greater responsibilities in Europe and the Middle East, enabling the US to concentrate on China and the Western Hemisphere, where Washington is intensifying its focus on drug cartels in South America.

In the Gulf, ongoing conflict with Iran has highlighted the extreme vulnerability of deployed US troops. At least 18 US servicemembers have lost their lives, which includes six fatalities resulting from an Iranian missile strike at Port Shuaiba in Kuwait. An inspector general's report examining the war's costs revealed that Iranian strikes caused damage and destruction to hundreds of buildings and structures at US installations located in Kuwait, Bahrain, Qatar, UAE, Saudi Arabia, Iraq, Oman, and Jordan, with Iran launching thousands of missiles at US bases across the region.

The newly released report also noted that Pentagon leadership has not yet finalized decisions regarding whether base and troop numbers will be restored to pre-war levels. According to the report, the Pentagon has not yet determined its future regional posture, how bases will be constructed, or the proportion of construction costs that allies and partners will fund. Meanwhile, The Washington Post reported that the Pentagon is exploring a potential redeployment of troops away from the Gulf region, where approximately 40,000 US personnel are typically stationed. An official informed the Post that Defence Secretary Pete Hegseth has not issued an order for a formal review of the force posture in the Middle East.

Additionally, CNN reported that the Pentagon plans to redeploy MQ-9 Reaper drones currently stationed in Africa to South America in support of expanded counternarcotics operations. In June, Mr Hegseth announced a six-month review focusing on Europe to evaluate the sizing and basing of US troops. This initiative is spearheaded by Elbridge Colby, undersecretary of defence for policy, who has long advocated for prioritizing the deterrence of China.

Among the options being evaluated by Pentagon officials, as reported by Reuters, is the potential withdrawal of roughly 25,000 troops from Europe—a prospect that concerns European and Nato officials who are already dealing with an increasingly confrontational Russia. Currently, the US maintains approximately 80,000 troops stationed throughout Europe. While downsizing force levels in Europe or the Middle East could redirect resources toward other strategic priorities, it simultaneously raises concerns regarding US deterrence capabilities and the steadfastness of Washington's commitments in both regions.

Senator Jeanne Shaheen, the ranking Democrat on the Senate Foreign Relations Committee, addressed a letter to Secretary of State Marco Rubio urging him to ensure that US diplomats participate in the Pentagon-led review of America's military presence in Europe. Addressed to Mr Rubio, who also serves as the national security adviser, the letter stated that diplomats, including US ambassadors stationed in potentially impacted nations, are currently excluded from the process. The letter noted that the Department of State, tasked with managing bilateral relationships, traditionally plays a key role in such reviews, yet feedback from European travel and discussions indicates US Ambassadors and Chiefs of Mission have been left out. A State Department official contested these claims, maintaining that diplomats are indeed being consulted.

Senator Shaheen warned that modifications to troop numbers would directly impact bilateral relationships that the State Department must manage, with Baltic states Estonia, Lithuania, and Latvia facing the highest stakes. European leaders have repeatedly cautioned against hybrid incidents—frequently blamed on Russia—that remain below the threshold of traditional military attacks but actively undermine regional security through actions such as sabotage, arson, and drone incursions.
