Brazilian President Luiz Inácio Lula da Silva used his address to the United Nations General Assembly on Tuesday to deliver a forceful defence of his country's sovereignty, warning that neither domestic nor foreign actors would be permitted to undermine October's presidential election. "Brazilian democracy belongs to Brazilians. Brazil will continue to be a sovereign country," Lula told the assembly in New York. "Nobody will turn us away from this path." Though he did not name the United States or President Donald Trump directly, his remarks were widely understood as a response to mounting tensions with Washington in the weeks before Brazilians go to the polls on October 4.

Lula is seeking a fourth, non-consecutive presidential term and faces his main rival in Senator Flávio Bolsonaro, son of former president Jair Bolsonaro, who is serving a 27-year sentence under house arrest following his conviction for an attempted coup. The Trump administration has publicly backed the Bolsonaro camp, and Washington recently designated two major Brazilian criminal organisations — the First Command of the Capital (PCC) and the Red Command (CV) — as foreign terrorist organisations. Lula rejected the move, and analysts have argued it was intended to portray him as soft on organised crime ahead of the vote. Trade tensions have also escalated, with Brazilian goods facing additional US tariffs of up to 37.5% under Sections 301 and forced-labour duties introduced this summer, though Brazil has held off retaliating while negotiations continue.

In his speech, which opened the general debate under a longstanding protocol that has assigned Brazil the first slot since 1955, Lula declared that "Brazil is nobody's backyard" and criticised what he called a resurgence of "hegemonic ambitions" and neo-colonial interference across Latin America. He said Brazil's electoral system was "modern and robust" and warned against disinformation campaigns targeting public debate during the campaign. On organised crime, he struck a careful balance — acknowledging the threat posed by gangs that "terrorise our communities" while insisting Brazil "will not outsource the responsibility of defending" its own borders and does not need "aircraft carriers watching our waters," but rather international cooperation to cut off weapons and money flows fuelling crime.

Lula's address ranged far beyond domestic politics, opening with a sharp rebuke of the United Nations itself. "The UN is failing in one of its highest missions: to save humanity from the scourge of war," he said, adding that the body's "credibility has never been lower." He attributed much of the paralysis to the Security Council's veto system, a position Brazil has held since the first General Assembly in 1946. He described 2025 as the year with the highest number of armed conflicts since World War II, called for a negotiated end to the Russia-Ukraine war, and referred to what he termed a "genocide" carried out by the Netanyahu government against civilians in Gaza — a characterisation that remains contested in international legal debate. He also called for greater regulation of technology companies and artificial intelligence.

The speech set up a striking contrast with the address that followed it, delivered by Trump, who celebrated US military power in the Western Hemisphere and announced new bases in Greenland, framed Iran's future in terms of a deal or annihilation, and praised American efforts to resolve the Gaza conflict. No bilateral meeting between the two leaders was scheduled. The juxtaposition — with Lula declaring that "war is not the continuation of politics by other means, but the complete breakdown of politics" while Trump said "while others talk, I act" — illustrated the depth of the diplomatic divide between two of the Western Hemisphere's largest democracies as Brazil's pivotal election draws near.
