US Announces ‘Southern Spear’ Mission In South America

U.S. Defense Secretary Pete Hegseth has unveiled Operation Southern Spear, a new military initiative aimed at countering what he describes as “narco-terrorist networks” operating across the Caribbean and northern South America. The mission, run through U.S. Southern Command (SOUTHCOM), is framed as a major effort to disrupt drug trafficking routes, strengthen maritime security, and expand U.S. influence in what the administration calls “America’s neighborhood.” While the Pentagon portrays it as a fresh strategic push, analysts note it is still unclear whether Southern Spear represents a true expansion of U.S. operations or merely a rebranding of long-standing activities focused on Venezuela and surrounding waters.

This news comes as the U.S. build up gets a new edition. The USS Gerald R. Ford, America’s most advanced aircraft carrier, is moving toward Venezuelan waters. The mission is officially framed as a counter-narcotics operation in the Caribbean. Analysts say the deployment also increases military pressure on Nicolás Maduro’s government. Venezuela has responded with a nationwide military mobilisation as tensions rise.The carrier’s arrival marks one of the strongest U.S. power projections in Latin America in decades.

According to extensive research at Reuters, the United States is rapidly rebuilding and expanding its military footprint across the Caribbean in preparation for potential operations involving Venezuela. A major focus is the revival of the long-abandoned Roosevelt Roads naval base in Puerto Rico, where crews are repaving taxiways, installing air-traffic systems, erecting tent facilities, and positioning Marine Corps aircraft — effectively transforming it back into a functional staging hub. Similar upgrades are underway at Rafael Hernández Airport in Puerto Rico and Henry E. Rohlsen Airport in St. Croix, which now host Reaper drones, radar systems, ammunition storage construction, and mobile air-traffic control towers. At sea, the U.S. has deployed at least 13 warships, a nuclear submarine, and support vessels, including destroyers, amphibious assault ships, and the USS Gerald R. Ford carrier strike group, now moving toward Venezuelan waters. Air operations have surged, with B-1B Lancers, B-52 bombers, F-35s, P-8 Poseidons, and dozens of C-17 cargo flights operating across the region.

Polymarket may be increasingly convinced that an attack is imminent, but it’s important to step back and consider the broader strategic context. For the Trump administration, the Western Hemisphere is not just another region – it sits at the heart of the long-standing Monroe Doctrine, the 19th-century U.S. policy asserting that North and South America fall firmly within Washington’s sphere of influence and should remain free of external great-power interference.What we’re seeing now is a modern revival of that doctrine. The deployment of U.S. naval power, intensified operations in the Caribbean, and growing pressure on Venezuela all signal a return to an older strategic mindset, one where the United States asserts dominance over the hemisphere and challenges any rival presence, whether from Russia, China, or Iran. In other words, this isn’t just about a single military strike or a one-off operation. It’s about re-establishing a geopolitical boundary that Washington believes slipped in recent decades and is now being forcefully redrawn more than 150 years after the original doctrine took shape.

This is an extremely costly build up that would not be done for no reason. The question is what kind of attack we will see if it does happen. Another question is whether the people and more importantly the army will support Maduro in the event of extensive U.S. airstrikes.
