Iran's accelerated production of near weapons-grade uranium puts more pressure on Trump as he's repeatedly said he's open to negotiations with the Islamic Republic while also increasingly targeting Iran's oil sales with sanctions as part of his reimposed "maximum pressure" policy.
Iran's Supreme Leader Ayatollah Ali Khamenei, who has final say on all state matters, in a speech in August opened the door to talks with the U.S., saying there is "no harm" in engaging with the "enemy."
However, more recently he tempered that, saying that negotiations with America "are not intelligent, wise or honorable" after Trump floated nuclear talks with Tehran.
Iran has maintained its nuclear program is for peaceful purposes only, but IAEA Director General Rafael Mariano Grossi has previously warned that Tehran has enough uranium enriched to near-weapons-grade levels to make "several" nuclear bombs if it chose to do so.
