The use of U.S. military force abroad has long been a central — and controversial — element of American foreign policy.
While large-scale ground wars have become politically and socially unpopular, the reliance on airstrikes, naval power, and limited operations has continued across administrations of both parties.
In 2025, under Donald Trump’s second administration, the United States again employed targeted military force in multiple countries. These actions were presented as necessary responses to security threats posed by non-state armed groups, particularly those linked to international terrorism or attacks on global commerce.
This in-depth analysis examines where U.S. force was used in 2025, which groups were targeted, why these decisions were made, and what they may mean going forward. Rather than advocating a political position, this post aims to provide a clear, fact-based framework for understanding the implications of these actions.
Overview of U.S. Military Actions in 2025
In 2025, confirmed U.S. strike operations occurred in three sovereign countries:
- Yemen
- Somalia
- Nigeria
These operations shared several defining characteristics:
- No formal declarations of war
- No large-scale U.S. troop deployments
- Reliance on air and naval power
- Targeting of non-state militant groups rather than national governments
This approach reflects a broader strategic preference for limited, high-impact military actions designed to minimize U.S. casualties while maintaining global influence.
Yemen: Campaign Against the Houthis
Background on the Houthis
The Houthis, formally known as Ansar Allah, are a powerful armed movement that controls significant portions of Yemen, including the capital, Sana’a. Over time, the group has developed sophisticated missile and drone capabilities, largely attributed to Iranian support.
Why Yemen Became a Target in 2025
In early 2025, Houthi forces escalated attacks on commercial shipping and military vessels in the Red Sea, one of the world’s most vital maritime trade corridors. These actions threatened:
- International shipping and supply chains
- Energy markets
- U.S. and allied naval assets
The Trump administration justified military action as a defense of freedom of navigation, a principle the U.S. has historically enforced regardless of administration.
Scope and Impact of the Strikes
Between March and May 2025, U.S. forces carried out a sustained campaign of air and naval strikes targeting:
- Missile and drone launch facilities
- Radar installations
- Weapons depots
- Command-and-control centers
Supporters argue these strikes degraded Houthi operational capacity. Critics counter that the campaign risked civilian casualties and widened an already devastating humanitarian crisis in Yemen.
Somalia: Targeting ISIS-Somalia
Who Is ISIS-Somalia?
ISIS-Somalia is a regional affiliate of the Islamic State operating primarily in northern Somalia. While smaller than al-Shabaab, the group has demonstrated the ability to conduct lethal attacks, recruit fighters, and destabilize local governance.
U.S. Rationale for Intervention
The Somali federal government requested U.S. assistance in combating ISIS-Somalia. U.S. officials cited:
- Counterterrorism obligations
- The prevention of regional instability
- The risk of Somalia becoming a safe haven for transnational attacks
Nature of the 2025 Operations
Throughout 2025, U.S. Africa Command conducted multiple precision airstrikes focused on:
- Senior leadership figures
- Training camps
- Weapons storage sites
These operations aligned with the long-standing U.S. strategy of supporting partner governments rather than assuming direct control of ground combat.
Nigeria: Strikes on ISIS-Linked Militants
Militant Landscape in Northwest Nigeria
Nigeria faces threats from multiple extremist groups, including factions aligned with the Islamic State West Africa Province (ISWAP) and locally organized militant networks operating in remote regions.
Why the U.S. Became Involved
In late 2025, Nigerian authorities identified militant camps believed to be planning imminent attacks on civilians and security forces. The U.S. provided intelligence and conducted precision strikes to:
- Disrupt planned attacks
- Degrade extremist infrastructure
- Strengthen security cooperation with Nigeria
December 2025 Airstrikes
On December 25, 2025, joint U.S.–Nigerian airstrikes targeted remote forest camps, destroying facilities used by ISIS-linked militants.
Nonpartisan Analysis: Continuity Across Administrations
Despite differences in rhetoric, the 2025 military actions reflect continuity rather than departure from prior U.S. administrations. Similar strategies were used under Democratic and Republican presidents alike.
Key points of consensus include:
- Preference for airstrikes over ground wars
- Framing operations as defensive or preventive
- Targeting non-state actors rather than governments
This suggests that U.S. military engagement abroad is driven more by institutional strategy and global commitments than by party ideology alone.
Legal and Ethical Considerations
The 2025 strikes reignited debates over:
- Presidential war powers
- Authorization for the Use of Military Force (AUMF)
- Civilian casualties and accountability
- Transparency and public oversight
While administrations often cite self-defense and existing authorizations, critics argue that congressional oversight has steadily eroded.
Future Implications
Looking ahead, several potential consequences emerge:
- Normalization of limited warfare: Targeted strikes may become an increasingly routine policy tool.
- Risk of escalation: Even limited actions can provoke retaliation or regional instability.
- Precedent-setting: Each use of force expands executive authority for future presidents.
- Humanitarian impact: Civilian populations may continue to bear indirect costs.
How the U.S. navigates these trade-offs will shape global perceptions of American power in the coming decade.
Call to Action
Understanding U.S. military actions should not be limited to policymakers and military officials alone. Citizens play a critical role in shaping foreign policy through:
- Staying informed beyond headlines
- Engaging in public discourse
- Holding elected officials accountable
- Asking hard questions about long-term consequences
Democratic oversight depends on an engaged and informed public.
