Watch live: Trump holds G7 press conference amid Iran deal blowback

The G7 summit in France has become a lightning rod for controversy, not least because of the geopolitical tensions simmering beneath the polished diplomatic veneer. Donald Trump’s impending press conference—broadcast live from Biarritz—arrives at a critical juncture, as his administration faces pushback over its approach to the Iran nuclear deal, a cornerstone of global nonproliferation efforts since 2015. The broader significance of this moment extends beyond the summit’s ceremonial photo ops; it underscores the erosion of multilateral consensus on nuclear diplomacy, a trend that predates Trump but has accelerated under his "America First" doctrine. The reimposition of U.S. sanctions after Washington’s withdrawal from the Joint Comprehensive Plan of Action (JCPOA) in 2018 has left European allies scrambling to preserve the deal through alternative trade mechanisms like INSTEX, which have so far yielded limited success. Trump’s refusal to engage in meaningful dialogue with Tehran—despite attacks on oil tankers in the Gulf and the seizure of a British-flagged vessel—has raised questions about whether the U.S. is deliberately isolating itself from the very alliances it helped build. Yet the story’s deeper context lies in the psychological and strategic realignment it reveals. For decades, the JCPOA was touted as a model for resolving crises through diplomacy, not coercion. Its unraveling has emboldened hardliners in Tehran while weakening moderates like President Hassan Rouhani, who staked his legacy on engagement with the West. Meanwhile, Trump’s embrace of maximum pressure tactics has drawn praise from some quarters for its perceived toughness but criticism from others for its lack of a clear endgame—whether regime change, negotiated surrender, or some other outcome remains deliberately ambiguous. The press conference will likely be parsed for signals on whether Trump intends to escalate military posturing or double down on economic pressure, but the absence of a coherent Iran strategy may be the most telling revelation of all. Looking ahead, the biggest open question is whether Trump’s transactional approach to alliances will force Europe to reconsider its dependence on U.S. security guarantees. If the JCPOA collapses entirely, the fallout could extend to other flashpoints, from North Korea to Venezuela, where Washington’s willingness to abandon negotiated frameworks sets a troubling precedent. For now, the world watches—not just for Trump’s words, but for the silence that follows them.
