As Venezuelan President Nicolás Maduro urges the international community to condemn an ongoing U.S.-backed effort to overthrow him and calls for peaceful negotiations with critics led by self-declared “Interim President” Juan Guaidó, the Cuban government—which supports Maduro—claimed on Thursday that the Trump administration is moving special forces closer to Venezuela “in preparation for a military adventure under the guise of a ‘humanitarian intervention.'”

In a lengthy statement denouncing the steps President Donald Trump and his allies have taken to oust Maduro—particularly National Security Advisor John Bolton and Republican Sen. Marco Rubio (Fla.)—the Cuban government said:

Pointing to a draft resolution that the Trump administration recently introduced at the U.N. Security Council that expresses concern about the humanitarian conditions of Venezuela, Cuba concluded:

The warnings out of Cuba come after Guaidó vowed on Tuesday that foreign aid—which has already begun arriving along the border with Colombia and Brazil—will enter Venezuela on Feb. 23 in spite of objections from Maduro, who has also characterized offerings of aid as part of a “political war of American empire” and “warmongering in order to take over” Venezuela.

Since Trump recognized Guaidó as Venezuela’s leader last month, he has appointed war hawk Elliott Abrams as a special representative to the country, repeatedly threatened military action if Maduro doesn’t turn over power to Guaidó, and seized billions of dollars in Venezuelan oil assets. In its statement on Thursday, Cuba charged U.S. actions are “causing serious humanitarian damage and harsh deprivation” to the people of Venezuela.

During a press conference late last month announcing the sanctions on Venezuela’s state-owned oil company, Bolton—in a move that critics said was “likely not an accident”—held up a notepad on which he had written “5,000 troops to Colombia.” A few days later, Bolton suggested that if Maduro keeps refusing to leave office, he could find himself locked up in a U.S. military prison at the Guantánamo Bay Naval Station in Cuba.
