U.S. Defense Secretary Pete Hegseth announced a six-month review of American troops stationed in Europe on Thursday [1].
The move signals a potential shift in the transatlantic security architecture, placing the burden of continental defense more heavily on European nations.
Speaking in Brussels, Belgium, Hegseth said the Pentagon will evaluate the current military footprint to determine if the U.S. is providing disproportionate support to its allies [2]. He said European NATO members have been overly dependent on the United States and have not accelerated their own defense investments [3].
The review comes as the U.S. pushes for a "NATO 30 reboot," urging allies to take primary responsibility for their own security [3]. Hegseth said future U.S. commitments to the region will depend on how quickly these allies strengthen their own defense capabilities [1].
There are currently about 80,000 U.S. troops stationed in Europe [4]. However, some reports indicate the Pentagon is required to maintain a minimum presence of at least 76,000 troops in the region [4].
Discrepancies exist regarding the specific drivers of the review. Some reports suggest the initiative is a response to European allies failing to provide U.S. forces with sufficient access to bases in Europe [1]. Other reports emphasize the lack of indigenous defense capability growth among member states [3].
Hegseth said the review process will last six months [1]. This period will likely involve assessments of strategic necessity, and the financial viability of maintaining current troop levels given the shifting geopolitical landscape.
“Future U.S. commitments will depend on how quickly NATO allies strengthen their own defence capabilities.”
This review represents a strategic pivot toward 'burden-sharing,' where the U.S. leverages its military presence to compel European allies to increase their own defense budgets. By questioning the scale of the 80,000-troop deployment, the U.S. is signaling that the era of unconditional security guarantees may be evolving into a transactional model based on reciprocal investment.
