The United States has directed all American embassies and consulates worldwide to launch coordinated campaigns against foreign propaganda, according to a cable signed by Secretary of State Marco Rubio on Monday.

The directive, obtained by The Guardian, instructs embassy staff to push back against what it describes as coordinated foreign efforts to undermine American interests abroad. The cable specifically endorses Elon Musk's social media platform X as an "innovative" tool to help combat disinformation.

The guidance suggests that embassies and consulates work alongside the US military's psychological operations unit to address what officials characterize as rampant disinformation. The cable provides detailed instructions for how diplomatic staff should respond to foreign propaganda efforts.

The directive represents a significant shift in how the State Department approaches information warfare, formalizing coordination between diplomatic missions and military psychological operations units. Embassy staff are being tasked with actively countering foreign narratives that officials believe damage American credibility and interests internationally.

The cable's explicit endorsement of X by name marks an unusual step for official US diplomatic communications, which typically avoid endorsing specific private platforms. The directive comes as the Trump administration has emphasized combating foreign influence operations as a key national security priority.
