On 15/8, the US Navy announced the deployment of the USS Iwo Jima, along with the USS Fort Lauderdale and USS San Antonio, by the 2nd Fleet for a "planned mission." However, the specific area of operation was not disclosed.

Two US defense officials later revealed to CNN that the USS Iwo Jima Amphibious Ready Group (ARG), along with the 22nd Marine Expeditionary Unit, comprising over 4,000 Marines and sailors, is being deployed to the waters of Latin America and the Caribbean to counter drug cartels in the region.

The Pentagon is also deploying a nuclear attack submarine, several P-8 Poseidon reconnaissance aircraft, destroyers, and a guided-missile cruiser for the anti-drug operation.

This is part of a military asset repositioning plan to Southern Command (SOUTHCOM), which has been underway for the past three weeks, according to US defense officials.

"This deployment is intended to deter threats to US national security, especially from groups that have been designated as narco-terrorist organizations," a third source, described as familiar with the recent deployment orders, revealed.

About a week ago, US media, citing informed sources, revealed that President Donald Trump had secretly signed a directive ordering the Pentagon to use military force against drug cartels in Latin America.

This is considered the US's most assertive move yet in confronting foreign drug cartels, potentially paving the way for direct military operations at sea and even on foreign soil.

Secretary of Defense Pete Hegseth previously suggested that the military prepare "credible" options to protect US security, prevent drug trafficking and illegal immigration, and ensure unimpeded access to the Panama Canal.

The US Department of Defense declined to comment on this information. Meanwhile, a White House spokesperson affirmed that President Trump's highest priority is protecting the country. "This motivates him to take bold action, putting some gangs and criminal organizations on the list of foreign terrorist organizations," the spokesperson said.

However, two US defense officials said that the current military deployment is "primarily for show of force," sending a message of deterrence rather than preparing for a direct attack on drug cartels.

One defense official acknowledged that US Marines are not specifically trained for counter-drug trafficking missions, so they need to work closely with the US Coast Guard if situations arise.
