Sources: 28. Developments: 3. During the 81st UN General Assembly, U.S. President Donald Trump delivered aggressive speeches targeting several nations and international institutions. Trump characterized Cuba as a ‘completely failed state’ on the verge of collapse and predicted that the government ‘will fall’ due to unprecedented pressure. He also stated that the United States is engaged in negotiations with Cuba, expressing confidence that freedom would eventually arrive on the island. These remarks led to diplomatic walkouts by both the Cuban and Iranian delegations. The Cuban delegation, led by Foreign Minister Bruno Rodriguez Parrilla, exited the hall immediately following Trump’s comments. Parrilla rejected the U.S. statements as ‘falsehoods’ and ‘slanders,’ asserting that the U.S. fails to recognize Cuba's right to be a sovereign nation. He further characterized the U.S. economic blockade and energy embargo as acts of ‘genocide’ and collective punishment. Cuban President Miguel Díaz-Canel also denounced the comments, accusing the U.S. President of being unable to justify the economic warfare waged against the Cuban people. This confrontation highlights escalating tensions between Washington and Havana following the return of the Republican administration to power. In addition to his comments on Cuba, Trump labeled Iran a former ‘Middle East bully,’ threatening to either negotiate for its reconstruction or ‘annihilate’ the nation. He also criticized the United Nations as a platform for ‘far-left’ globalist agendas and described the International Criminal Court (ICC) as an ‘uncontrollable’ and ‘rogue’ institution. Regarding technology, Trump rejected international AI regulation, announcing that U.S. government documents will transition from using the term ‘AI’ to ‘super intelligence’ (SI). ## Claims - Donald Trump stated at the UN General Assembly that the Cuban communist government will fall.
