Iran's foreign minister arrived in Geneva for a third round of high stakes negotiations with the United States over Tehran's nuclear program, as President Donald Trump warned that military action remains an option if no agreement is reached. Washington is demanding that any new deal remain in force indefinitely, rejecting time limits that were included in the 2015 agreement brokered under former president Barack Obama.

Significant gaps persist between the two sides. The United States is calling for Iran to halt all uranium enrichment, while Tehran insists it has the right to continue. American officials have signaled they eventually want to address Iran's ballistic missile program and its support for armed proxy groups, though the current focus remains on nuclear restrictions.

Tensions have escalated alongside the diplomacy. The United States has expanded its military presence in the Middle East, deploying additional advanced stealth fighter jets and support aircraft to Israel, while also imposing new sanctions targeting Iranian oil sales and weapons production networks. Iran has responded with threats against Israel and American targets if it is attacked, even as its president expressed cautious optimism about the talks.

The outcome of the Geneva negotiations is expected to weigh heavily on Trump's decision about whether to pursue a diplomatic resolution or consider military action, amid growing regional instability and international travel disruptions.
