Washington's Cuba reckoning: indictment and the anatomy of a sixty-year failed strategy
The Trump administration escalated its pressure on Havana on 22 May 2026, when Secretary of State Marco Rubio formally designated Cuba a "national security threat" to the United States, hours after federal prosecutors unsealed an indictment against former Cuban president Raúl Castro. The dual move — criminal charge plus national security formalisation — represents the most aggressive US action against the island since the 1962 Cuban Missile Crisis, and raises a question that six decades of successive administrations have preferred to defer: what does a maximalist Cuba policy actually achieve?
The indictment targets a figure who formally stepped down from Cuba's presidency in 2018 and who was already subject to US Treasury sanctions. The charges, according to reporting by The Indian Express, stem from allegations relating to the Cuban government's role in sheltering and financially supporting members of Colombia's FARC guerrilla movement — a relationship that Colombian and US intelligence services have tracked for years. The designation of Cuba as a national security threat, rather than simply a problematic state sponsor of terrorism, is a deliberate escalatory step: it unlocks a broader menu of economic, financial, and diplomatic tools and signals that the administration views engagement as not merely futile but dangerous.
Rubio, speaking from the State Department, said Washington remained "open to talks" with Havana but characterised the prospect of a negotiated solution as unlikely. That framing — keeping a door technically ajar while foreclosing the conditions for walking through it — has defined US Cuba policy under multiple administrations. What differs this time is the rhetorical register and the speed of escalation.
The indictment's target and what it tells us
Raúl Castro, who formally succeeded his brother Fidel in 2006 and held the presidency until 2018, has been a US sanctions target since 2008. The new indictment does not appear to allege personal involvement in terrorism in the conventional sense. Rather, prosecutors appear to be building a case around the financial infrastructure the Cuban state allegedly maintained to funnel resources to the Revolutionary Armed Forces of Colombia — a group that has itself undergone partial demobilisation but retains armed factions. Whether a criminal case centred on historical support for a now-diminished insurgency can produce any practical outcome is unclear: Raúl Castro is 94 years old, remains in Havana, and the United States has no extradition treaty with Cuba.
The indictment's practical impact is therefore primarily symbolic — and symbolically it does significant work. By formally naming a former head of state as a criminal defendant in a US federal court, Washington signals that the normalisation process opened under Barack Obama in 2015–2016 is not merely paused but actively reversed. Obama's 2014 decision to restore diplomatic relations with Havana was premised on a theory of diplomatic leverage: that reduced hostility would make Cuban authorities more willing to negotiate political reform. The Trump administration's second-term team has rejected that premise entirely.
A policy that has outlived its own logic
The core problem with the US approach to Cuba is one that is rarely stated in official Washington discourse: six decades of economic pressure, diplomatic isolation, and regime-change signalling have failed to produce regime change. Cuba today retains a functioning, if struggling, state apparatus, a military that remains the country's most powerful institution, and a political system that has managed two transitions of power without the kind of collapse that US policy has consistently anticipated.
This is not a defence of the Cuban government's human rights record, which includes restrictions on assembly, expression, and political competition that most democracies would consider incompatible with basic freedoms. It is simply an observation that the policy instrument chosen to address those concerns — comprehensive economic pressure — has been applied at maximum intensity for sixty years and has not worked. The embargo, now codified into law, bans most US trade with Cuba and penalises third-country companies that do business with Cuban entities. The Helms-Burton Act of 1996 extended those extraterritorial provisions. The result has been a managed humanitarian deterioration that has produced genuine suffering — shortages of medicines, food, and basic goods — without producing political change.
What the administration appears to be doing now is doubling down on a losing hand. The national security threat designation will enable further financial restrictions and may complicate the limited remittance flows that currently sustain parts of the Cuban civilian economy. It may also make it harder for Cuban families to access basic financial services as US secondary sanctions on correspondent banks tighten. Whether this creates political pressure on the Cuban government or simply deepens the precarity of ordinary Cubans remains to be seen — but six decades of evidence points toward the latter.
The regional context — and the limits of Washington's leverage
What complicates the US position further is the shifting terrain of Latin American politics. Where once Washington could count on a set of allied governments willing to coordinate on Cuba policy — and did so through the Organisation of American States — that coalition has frayed significantly. Several Latin American governments, across the political spectrum, have questioned the wisdom of unconditional US pressure on Havana, particularly when it produces humanitarian consequences for civilians. The OAS, once a reliably anti-Cuba institution, has itself become a site of institutional conflict over its direction and legitimacy.
The Trump administration's second-term foreign policy has been characterised by a willingness to challenge established multilateral arrangements, often unilaterally. On Cuba, that posture aligns with the most hardline elements of the Republican foreign policy establishment. But it sits uneasily with the administration's stated goal of securing deals — with Iran, with North Korea, with Russia — on terms that would have seemed implausible under previous dispensations. Cuba, uniquely among US adversaries, has not been offered a negotiating track even theoretically. That absence is not accidental; it reflects a determination that no deal with Havana is possible, or perhaps desirable.
What comes next — and who bears the cost
The practical consequences of the national security designation will unfold over the coming months. Secondary sanctions on third-country entities doing business with Cuban state entities are likely to intensify. The administration has hinted at further actions, per Deutsche Welle's reporting on 22 May, though the specific contours of those measures have not been publicly articulated. The indictment of Raúl Castro, meanwhile, sits in legal limbo until and unless the Cuban government somehow cooperates with US extradition — a prospect so remote as to be functionally meaningless.
The cost of that limbo falls on two distinct populations. The first is the Cuban government and its military elite, who face further financial pressure on an economy already under severe strain. The second, and larger, is the Cuban civilian population — estimated at roughly eleven million people — who are the primary victims of an embargo that has been tightened repeatedly over six decades and which shows no credible path to the political outcome it was designed to produce.
That discrepancy — between the stated goal of the policy and its demonstrated results — is the uncomfortable question that the Rubio statement on 22 May did not address. It may be that the administration believes that enough pressure, applied for long enough, will eventually produce collapse. That theory has been operative since 1962. It has not yet been vindicated. What has been vindicated is the capacity of the Cuban state to absorb punishment and persist — and the willingness of US policymakers to keep applying it regardless of outcome. The designation of Cuba as a national security threat does not change that dynamic. It simply extends it.
