America is at war on the border.

The Pentagon again calls itself the Department of War. Fentanyl is treated like sarin. Veterans sleep in tents while a promised mega-campus waits to be built in Los Angeles. President Donald Trump spent 2025 rewriting the country’s rules of war. Orders out of Washington put troops on the southern border under an invasion mission. They revived the Department of War name at the Pentagon, treated fentanyl like a battlefield weapon, pushed U.S.

Space Force toward combat in orbit, and have promised 6,000 beds for homeless veterans in Los Angeles. The shift reaches from the Rio Grande to the moon, pulling the military deeper into border security, drug policy, space and homelessness as Trump has navigated from campaign rhetoric to a more stringent national... Trump’s 2025 agenda didn’t just change policy; it redrew the map for how the administration defines threats. Synthetic opioids, homelessness, migration and lunar exploration now sit inside the same national security conversation as carrier groups and missile defense, reframing domestic issues as potential fronts in broader conflict. Congress has not passed legislation reversing or codifying the Department of War renaming or related directives. Committees in both the House and Senate requested 2026 briefings on border deployments, fentanyl policy, lunar infrastructure, and use of Title 10 powers in nontraditional missions.

The upcoming year will test whether the directives become durable doctrine through budgets and case law, or remain executive experiments vulnerable to judicial review or political reversal. Supporters said the new objectives delivered clarity about how the administration plans to project strength. Critics, however, have argued that the "war" framing blurs legal lines on domestic deployments and centralizes military power in crises historically handled by civilian agencies. National Defense Areas (NDAs) are military installations designated by the second Trump administration at the Mexico–United States border which are operated by the US Department of Defense, where troops can search and detain.[1][2][3][4][5][6][7][8] Joint Task Force-Southern Border assumed control of the southern border mission from Joint Task Force North on March 14, 2025. The southern border mission is supported by thousands of service members as part of the expanded role of the pentagon in the Trump administrations border priorities.[9][10][11]

The creation of these NDAs was outlined in a National Security Presidential Memorandum (NSPM-4) issued on April 11, 2025, titled "Military Mission for Sealing the Southern Border of the United States and Repelling Invasions."... The first zone, the New Mexico National Defense Area as part of Fort Huachuca.[13][14][non-primary source needed] A second National Defense Area, The Texas National Defense Area (TXNDA), was announced as part of Fort Bliss.[15][16][17][18][non-primary... The establishment of NDAs is authorized under existing laws, specifically 50 U.S.C. § 797 and 18 U.S.C. § 1382. These laws allow military personnel to remove trespassers from military installations.

In May 2025, Federal judge Gregory B. Wormuth dismissed charges against 100 people on account that "migrants couldn’t know they were trespassing".[29][30] FORT BLISS, Texas — Joint Task Force-Southern Border, a newly-announced headquarters element from the 10th Mountain Division, assumed control of the southern border mission on March 14, 2025. “This is an important step in the whole-of-government efforts to seal the southern border and maintain U.S. sovereignty and territorial integrity,” said Gen. Gregory M.

Guillot, commander of U.S. Northern Command (USNORTHCOM). “Joint Task Force-Southern Border will lead as both the synchronizer of all joint capabilities and the land force commander for USNORTHCOM as we conduct operations on the southern border, building upon the excellent foundation... The transfer of authority from Joint Task Force-North to Joint Task Force-Southern Border aligns efforts under a single, joint task force, allowing for more effective and efficient Department of Defense (DoD) operations. Following President Trump’s Executive Order “Protecting the American People Against Invasion,” the DoD has made protecting the southern border its top priority. It also supports the Department of Homeland Security (DHS) and U.S Customs and Border Protection (CBP) in ensuring 100% operational security.

The mission is to conduct all-domain operations to control the U.S. southern border in support of CBP to protect the territorial integrity of the United States. President Donald Trump is authorizing the U.S. military to take jurisdiction over federal lands along the southern border to help enforce his immigration agenda. Trump issued a memorandum to the secretaries of Defense, Interior, Agriculture and Homeland Security late Friday titled "Military Mission for Sealing the Southern Border of the United States and Repelling Invasions." The order directs the secretaries to facilitate the transfer of jurisdiction over federal land along the border so military activity along the border can "occur on a military installation under the jurisdiction of the...

The lands would be designated as "National Defense Areas." The order names the Roosevelt Reservation, a strip of land along the U.S. border with Mexico in California, Arizona and New Mexico, as one of the federal lands slated for military control. The Roosevelt Reservation is an easement roughly 60 feet wide, or "the distance from home plate to the pitcher’s mound,” said Adam Isacson, director of defense oversight for the Washington Office on Latin America...

The Roosevelt Reservation runs along the southern border from the Pacific Ocean to the eastern border of New Mexico. Building America’s Golden Age In 1907, President Theodore Roosevelt’s Presidential Proclamation established the Roosevelt Reservation in order to keep all public lands along the USA-Mexico border in California, Arizona, & New Mexico “free from obstruction as a protection...

This is a 60-foot-wide strip of land, 632 miles long, owned by the United States Federal Government. The newest effort from the Trump Administration to secure the southern border includes authorizing the military to take control of public land along the border. “The complexity of the current situation requires that our military take a more direct role in securing our southern border than in the recent past,” a White House memorandum dated April 11th stated. In a historic move, the Department of Defense took over control of the Roosevelt Reservation from the Department of the Interior. This memo gives the Pentagon full authority to build barriers, install detection equipment and even create what are being called “National Defense Areas” along that strip, creating active-duty military space. DoD Secretary Pete Hegseth has 45 days to assess this first phase and could expand it at any time.

That means even more land, more troops and more federal force possibly coming to the southern border. The Roosevelt Reservation will be treated as Department of Defense property, meaning those who walk on the land could be subject to detention and likely legal action.
