KEY POINTS FROM THIS ARTICLE — The largest U.S. military buildup near Venezuela in nearly 40 years is prompting commercial airlines to reroute around the nation’s airspace, and prompting Congress toward a debate over war powers on the mission’s lawfulness as of Dec. 6, 2025. Deployed under Operation Southern Spear and described as an anti-drug mission, the increased U.S. presence and more than 20 strikes on small boats are causing concern that President Donald Trump may be moving toward direct conflict with President Nicolás Maduro’s government.
Venezuela’s buildup hits a new stage.
In recent months, as world attention has been consumed by the coronavirus pandemic and protests about police violence in the United States, the U.S. military has surged warships, soldiers and fighter jets into the southern Caribbean with an intensity not seen in years — perhaps a decade or more. The show of force is so overwhelming that military analysts say even if President Trump decided to launch strikes against Venezuelan targets and topple Nicholas Maduro’s regime, he may struggle to find sufficient support at the Pentagon.
The deployment is to involve the USS Gerald R. Ford aircraft carrier, destroyers, cruisers, amphibious ships, as well as drones and F-35 fighter jets operating from Puerto Rico and its adjacent waters.
Previous reporting by such outlets as the Financial Times, Reuters and The Washington Post described an initial push of seven to eight U.S. warships and between 4,500 and 10,000 personnel massing near Venezuela in late August, ostensibly to counter drug-running operations but in reality showing pressure on Maduro’s grip on power.
That previous crescendo has now solidified into what one new Trump administration strategy document refers to as a long-term assertion of U.S. hegemony in the Western Hemisphere, including the explicit resurrection of the Monroe Doctrine.
Venezuela’s airspace becomes a no-go zone.
The military manoeuvres have quickly spilt over into civil aviation. An analysis of flight data by Reuters estimated that roughly half as many jets have been passing over Venezuela since the U.S. Federal Aviation Administration said on Nov. 22 that flights could be unsafe, leading many airlines to reroute through Colombian and neighbouring airspaces, where flight information is coordinated using the same protocols used in the United States. The analysis also revealed that flights were rerouted entirely around Venezuelan airspace.
Aviation specialists say the warning came against a backdrop of GPS interference, heavy U.S. reconnaissance and an uptick in Venezuelan military posture — including air-defence systems capable of reaching civilian cruise altitudes. An industry briefing on new FAA airspace warnings for Venezuela and Puerto Rico called upon carriers to “do everything in their power” to stay out of the SVZM/Maiquetía flight area beyond what is “absolutely necessary,” citing that numerous major airlines had already discontinued services, with Caracas revoking operating permits for several foreign operators in response.
Venezuela front tests U.S. war powers.
At sea, American forces have reported conducting more than 20 strikes on suspected drug-smuggling boats in the Caribbean and eastern Pacific since early September, resulting in over 80 fatalities, according to records cited by the Trump administration and independent media timelines. An Associated Press chronology of the escalation details 22 known strikes and notes increased congressional concern following reports that survivors from the first incident were killed in a subsequent strike.
The White House maintains that it is in an “armed conflict” with drug cartels, and does not need new authorisation to use force, but lawmakers of both parties say the campaign viscerally resembles an undeclared war focused on Venezuela. This week, a bipartisan group of senators introduced a privileged resolution that would constrain votes on ways to prohibit him from directing land strikes in the country without clear congressional consent, ratcheting up a war powers fight that had been building for months.
The measure builds on S.J.Res. 90, a joint resolution asserting that Congress has not declared war on Venezuela and calling for the withdrawal of U.S. forces from hostilities where there is no specific congressional authorisation. But while that previous effort floundered on the Senate floor, the new resolution must get a vote within days under rules of the chamber, providing a public test of support for what has become Trump’s strategy.
Venezuela crisis fuels regional anxiety.
That has not stopped regional governments from sounding the bells of alarm. Brazil’s president, Luiz Inácio Lula da Silva, has said his country is “very worried” about the U.S. buildup near Venezuela and worries that this may lead to a conflict, while neighbours in the Caribbean measure cooperation with U.S. drug missions against memories of past interventions. A Council on Foreign Relations map of the U.S. military presence near Venezuela points out that air and naval deployments now run from Puerto Rico to Trinidad and Tobago, in air corridors that have long been used by commercial flights.
But the pressure is also remoulding regional politics. A recent Reuters report suggested that “elements within the Cuban regime” have made back-channel overtures to American officials to game out what a post-Maduro region might look like, while publicly, Havana has slammed the buildup as an “exaggerated and aggressive” threat to Venezuela. Meanwhile, Trump’s new National Security Strategy explicitly revives the Monroe Doctrine and presents the Western Hemisphere — and the crisis in Venezuela — as a test of U.S. resolve to uphold its sphere of influence.
For now, diplomats and analysts suggest neither Washington nor Caracas appears to seek a large-scale conflict. However, with heavily armed ships and aircraft positioned near Venezuela and airspace shared by military and commercial jets in narrower corridors, they caution that an error or a mistaken response could escalate an anti-drug operation into a significant regional standoff.
