Congressional Republicans inserted provisions in 2027 defense bill to prevent further troop cuts.
Defense Secretary Pete Hegseth announced on June 18 that the Pentagon will conduct a six-month review of American military presence in Europe. Hegseth warned that the U.S. will cut funding to NATO’s operating budget if European allies do not meet military spending commitments. The review signals the Trump administration may reduce U.S. troop levels on the continent, alarming European partners who rely on American security guarantees.
What the Pentagon Will Review
Air Force Gen. Alexus Grynkewich, head of U.S. European Command, will lead the assessment over six months. The review will examine America’s core military posture, basing arrangements, and access to European airspace. Hegseth stated the review has no predetermined outcome but aims to ensure NATO moves toward European-led defense and that U.S. forces are positioned for global needs.
Hegseth’s Demands on NATO Allies
Hegseth threatened to cut NATO funding if allies do not increase military spending. He criticized European nations for denying U.S. forces access to bases needed to launch operations against Iran, calling the denial “shameful.” Hegseth told NATO counterparts that some countries will “fail” the review while others will “pass with flying colors.”
Congressional Pushback on Troop Cuts
Republican lawmakers have inserted provisions into the 2027 National Defense Authorization bill to prevent further troop reductions. These provisions require a risk assessment from military leaders about the impact of any proposed U.S. troop cuts. The lawmakers argue they were not consulted about previous reductions and cite the ongoing Russian threat to Europe as reason to maintain force levels.
Europe Braces for Uncertainty
The announcement surprised European allies and Canada, who have faced conflicting signals from Washington about U.S. military commitments. The U.S. is immediately cutting the number of assets it would activate for Europe in a crisis. German Chancellor Friedrich Merz acknowledged that Europe must take greater responsibility for its own defense but noted allies have long expected U.S. troop withdrawals.
Final Thoughts
The Pentagon’s six-month review signals the Trump administration intends to reduce U.S. military commitments in Europe. Investors in defense contractors and European economies should monitor whether Congress can block deeper cuts and how NATO allies respond to increased spending demands.
