A Cuba-linked activist network prepared a nationwide rapid-response plan to mobilize protesters across the United States within 24 hours if the American military launches an attack against the island nation, according to an internal document obtained by the Washington Examiner.

The National Network on Cuba (NNOC) said its "National Rapid Response Plan" is designed to organize demonstrations in major cities, at federal facilities and even at sporting events to increase political pressure on the U.S. government.

"The goal is to make it politically and materially costly for the U.S. government to wage war on Cuba," the document stated.

According to the plan, activists in large metropolitan areas would assemble "big, broad coalitions" for rallies outside federal buildings and other prominent locations.

Organizers in smaller communities are encouraged to use "power mapping" to identify local protest targets, distribute flyers and banners, and coordinate messaging through social media using shared graphics and branding.

The document also calls on supporters to begin building rapid-response teams before any military action occurs.

"That is an action that puts pressure on the ruling class," the group wrote. "Publicize it! Announce it!"

The plan identifies potential protest sites, including federal courthouses, military bases, recruiting offices, federal agencies, and Immigration and Customs Enforcement facilities, saying demonstrations at ICE locations would connect "Cuba solidarity to anti-ICE/immigrant defense work."

The document also directs activists to a nationwide map of U.S. military installations compiled by the left-wing Black Alliance for Peace.

The NNOC, based in Washington, promotes travel to Cuba and solidarity with the communist government with assistance from the Cuban Institute for Friendship with the Peoples (ICAP), a Cuban government organization that the State Department sanctioned in June, according to the Washington Examiner.

Secretary of State Marco Rubio announced sanctions against ICAP, describing it as a propaganda arm of the Cuban regime. The sanctions were followed by the arrest of a Cuban national and members of his family for deportation proceedings over alleged ties to the organization.

The NNOC and the Venceremos Brigade are also planning to take some 150 Americans to Cuba in August to commemorate what would have been former Cuban leader Fidel Castro's 100th birthday.

The protest blueprint comes as the Trump administration has intensified pressure on Havana through economic sanctions, national security measures and legal action against current and former Cuban officials.

President Donald Trump has floated the idea of a "friendly takeover" of Cuba and his administration has pursued legal efforts against former Cuban President Raul Castro.

In May, the Justice Department pledged to pursue Castro in connection with allegations surrounding the 1996 shootdown of two civilian aircraft operated by the humanitarian group Brothers to the Rescue.

Meanwhile, Rubio has said the U.S. would provide Cuba with up to $100 million in assistance if the island establishes a government more aligned with the U.S.

The NNOC argues the U.S. embargo itself amounts to military aggression and urged supporters to prepare for demonstrations regardless of whether military action materializes.

"Cuba is already being attacked. The blockade is an act of war," the document states. "Even if boots don't go on the ground tomorrow we have to be proactive."
