Despite more than three decades of near-unanimous UN General Assembly resolutions, the U.S. embargo on Cuba continues. What does this show about the limits of the UNGA?

The UN Charter allows the General Assembly only to "make recommendations" (Articles 10–11) [2]. The U.S. has disregarded 33 consecutive resolutions against its Cuba embargo [1], and in 2026 it added a fuel blockade [5]. The Assembly can set norms, but it cannot enforce them.

Limits exposed by the Cuba case

• Non-binding mandate: UNGA resolutions carry no legal obligation and no penalty for ignoring them [2], unlike UNSC decisions under Chapter VII.
• Domestic law prevails: The LIBERTAD (Helms-Burton) Act, 1996, wrote the embargo into U.S. law. Lifting it requires Congress, so even a willing President cannot fully comply [3].
• Power asymmetry: No mechanism exists to enforce votes against a permanent UNSC member. A 187-2 majority in 2024 changed nothing [1].
• Gains are reversible: The U.S. abstained for the first time in 2016 [4], but later Presidents reversed course. A January 2026 executive order threatened tariffs on any country supplying oil to Cuba [5].
• Politicised voting: Support fell to 165 in 2025 because Ukraine, Argentina, Hungary and others voted "No". This reflected alliances over the Ukraine war, not a new view on sanctions [1].
• Weak humanitarian leverage: UN experts call the blockade "energy starvation" and "unlawful" [5]. A Special Rapporteur found that banks' over-compliance blocks even exempt food and medicine [6]. The Assembly cannot compel relief.

Yet the UNGA is not irrelevant

• Legitimacy: Near-unanimous votes delegitimise unilateral, extraterritorial sanctions. Collective pressure preceded the 2016 U.S. abstention [4].
• Agenda-setting: In July 2026 the Assembly voted 136-9-30 to debate the blockade despite U.S. objections [7].
• Norm guardian: It reaffirms the Charter's bar on the "threat or use of force" amid U.S. takeover threats [7].

The Cuba case shows that the UNGA acts as the world's conscience but not its enforcer. Revitalising the Assembly, coordinating follow-up with the Human Rights Council and advancing UNSC reform can narrow the gap between its voice and actual outcomes. This would serve sovereign equality and SDG 16's goal of effective, accountable institutions.
