U.S. Senator Marco Rubio (R-FL) said Thursday that Cuba represents a national security threat to the United States during a press briefing in Washington, D.C.

The remarks signal a hardening of the U.S. stance toward Havana, potentially limiting the window for diplomatic engagement and increasing tensions between the two nations.

Rubio said that Cuban leaders will not be able to "buy time" regarding their current political and security posture. He said that the likelihood of a peaceful agreement between the U.S. and Cuba is not high.

During the briefing, Rubio cited past hostile actions to justify his assessment. He specifically referenced the 1996 downing of two civilian planes [1], an event that resulted in the deaths of U.S. citizens [1].

Rubio said that the history of such actions underscores why Cuba is viewed as a threat. He said that the persistent nature of these tensions makes a diplomatic resolution improbable at this time.

The senator's comments come amid ongoing scrutiny of the Cuban government's relationship with the U.S. and its internal political structure. By framing the island as a security risk, Rubio aligns his position with a policy of maximum pressure on the Cuban leadership.

While some reports have suggested different official titles for Rubio or legal actions against former Cuban President Raúl Castro, these claims are not supported by the primary records of the briefing.

"Cuba is a national security threat."

The rhetoric from Senator Rubio reflects a shift toward a more confrontational U.S. policy toward Cuba, emphasizing historical grievances and security risks over diplomatic outreach. By invoking the 1996 plane downings, the U.S. is grounding current security concerns in past military aggression, which likely precludes any immediate thaw in relations.
