It is a significant moment in the long and complicated relationship between the United States and Central America. Guatemala has agreed to allow American forces to carry out joint military strikes inside its territory targeting drug trafficking organizations and gangs, according to reporting confirmed by multiple officials familiar with the discussions.
The agreement represents one of the most aggressive escalations of U.S. counternarcotics operations in decades and marks a new chapter in a campaign that Washington has been building with growing intensity since September 2025.
The backdrop for this agreement is not hard to understand. At the start of 2026, coordinated gang violence erupted across Guatemala in a crisis that shook the country to its core. Prisoners affiliated with the gang Barrio 18 took over three prisons, seizing more than 40 security personnel as hostages. Within hours, gang members in multiple neighborhoods of Guatemala City launched coordinated attacks on the National Civil Police, killing nine officers and prompting President Bernardo Arévalo to declare a nationwide state of emergency.
Arévalo responded by launching Plan Sentinel, deploying heavily armed troops on armored personnel carriers into northern neighborhoods of the capital long controlled by Barrio 18 and MS-13. It was the first time such a coordinated military and police operation had been mounted in those areas. The government wanted to demonstrate that a center-left administration could confront organized crime as forcefully as any right-wing government in the region, and without the human rights abuses that have accompanied crackdowns elsewhere.
But internal operations were not enough. Following a high-level meeting between Guatemalan and Trump administration officials earlier this year, Guatemala announced what officials described as a strong alliance, with the United States gaining authorization to carry out joint strikes targeting drug trafficking groups operating inside Guatemalan territory. The agreement fits within the broader framework of the Trump administration’s dramatically escalated war on cartels, which Washington has been waging with lethal force across the Western Hemisphere under the banner of Operation Southern Spear.
That operation, launched in September 2025, has used U.S. Navy, Air Force, Marine Corps, and Coast Guard assets to strike suspected drug trafficking vessels in the Caribbean Sea and Pacific Ocean. By late March 2026, at least 163 people had been killed in more than 47 strikes on 48 vessels, with the campaign expanding to include land targets inside Venezuela. Guatemala is now the first country to formally invite that same approach onto its own soil.
The Trump administration has framed these operations as part of a multi-front strategy aimed at dismantling cartel networks wherever they operate, on land or at sea, with the White House expected to release additional details on cooperative agreements with Latin American partners and expanded authorities for U.S. Southern Command in the coming weeks.
The Guatemala agreement does not exist in a regional vacuum. Guatemala became the third Latin American government to declare a state of emergency against gang violence in a matter of months, reflecting a broader regional shift in which even left-leaning governments are moving toward harder security postures under pressure from Washington and their own voters. Guatemala, Honduras, and Costa Rica are among those planning megaprisons modeled on El Salvador’s CECOT detention complex.
The legal and diplomatic questions surrounding joint strikes on sovereign territory are not simple. Critics have raised concerns about accountability, the threshold of evidence required before lethal force is applied, and the precedent being set across a region where the U.S. military footprint has historically generated deep suspicion. Guatemala’s own civil war, which ended in 1996 after decades of violence in which American involvement played a documented role, remains a living memory for much of the population.
What is clear is that the political calculus in the region has shifted. Projecting toughness against gangs and cartels is a winning position in 2026, and Guatemala under President Arévalo has decided that partnering with Washington on lethal operations inside its own borders is preferable to managing the crisis alone.
