The U.S. military has struck at least 45 small boats in the eastern Pacific and Caribbean under Operation Southern Spear between September 2025 and March 2026, leaving 156 people killed or presumed dead, according to a congressional report covering the operation's first two quarters. Strikes have continued beyond that reporting window, with confirmed incidents in April and May 2026.

The operation is run by Joint Task Force Southern Spear, which sits under U.S. Southern Command (SOUTHCOM). Until recently, the chain of command for individual strikes ran through Secretary of Defense Pete Hegseth — a January 23, 2026 strike was conducted at his direction. By spring, authority had shifted to SOUTHCOM's commander, Gen. Francis L. Donovan, who directed strikes on April 15 and May 8, 2026. The delegation of strike authority down the chain of command — from the civilian secretary to a geographic combatant commander — suggests the operation has shifted from ad hoc to institutionalized.

The legal architecture underpinning the strikes dates to January 20, 2025, when President Trump signed a presidential order designating certain cartels as Foreign Terrorist Organizations (FTOs) and Specially Designated Global Terrorists (SDGTs). That dual designation is load-bearing. FTO status triggers criminal liability for material support; SDGT designation activates Treasury's blocking powers. Together, they also provide the policy predicate for treating cartel-linked vessels as enemy combatants rather than civilian law-enforcement targets — a categorization that moves the use of force from the law-enforcement paradigm into the laws of armed conflict.

SOUTHCOM press releases consistently describe struck vessels as operated by "Designated Terrorist Organizations," tracking directly to the January 2025 order. A December 4, 2025 strike targeted a vessel confirmed to be carrying illicit narcotics along a known trafficking route in the Eastern region. The May 8 strike is the most recent confirmed engagement.

The casualty figures are consequential. Reuters reported three killed in the April 16 eastern Pacific strike. In October 2025, five alleged smugglers died across two vessel strikes. AP reporting from June 17, 2026 documents additional incidents resulting in one and three deaths respectively. The aggregate — 156 killed or presumed dead through March alone — makes this among the deadliest sustained U.S. military interdiction campaigns in the Western Hemisphere in recent memory, though the administration frames it entirely as counterterrorism.

That framing has diplomatic dimensions. Secretary of State Marco Rubio and Mexican Foreign Secretary Juan Ramón de la Fuente held a joint press availability in September 2025 focused specifically on U.S. military-grade weapons reaching narcoterrorist organizations in Mexico and Latin America. The conversation acknowledged a shared threat picture even as it papered over the deeper tension: Mexico has not consented to U.S. lethal operations in its maritime approaches, and the strikes occur in international waters precisely to sidestep that jurisdictional question.

The White House has been explicit about its framing. A January 2026 statement from Rubio declared that Trump "delivered justice to terrorists" on September 23, 2025 — language calibrated to the FTO designation rather than drug interdiction law.

The broader picture here is one of institutional normalization. A campaign that began with a White House-level announcement in late September 2025 is now generating routine SOUTHCOM press releases. The reporting cadence, the congressional reports, the delegated authority — these are the administrative signatures of a durable program, not a temporary surge. What remains genuinely open is the legal scrutiny: no federal court has yet tested whether the FTO designation is sufficient to authorize lethal force against individuals aboard vessels in international waters absent an imminent threat finding. Congress has received the statutory reports, but there has been no public debate over the authorization, rules of engagement, or proportionality standards being applied. Given the pace — 45 vessels in six months — that gap is unlikely to stay quiet.
