“Based on the fact that there’s a substantial chance of negotiations that may or may not take place with Iran in the near future, I will make my decision whether or not to go within the next two weeks,” Trump said in a dictated message, according to White House spokeswoman Karoline Leavitt.

Iran maintained Friday it won’t negotiate with the US while an Israeli assault continues. The only way to end the imposed war is to “unconditionally stop” the enemy’s aggression, Iranian President Masoud Pezeshkian said Friday in a post on X.

Oil prices fell following a report from Reuters that Iran is ready to discuss limitations on nuclear enrichment, but will not consider stopping entirely. That puts the country’s leadership at odds with Trump, who has called for zero enrichment.

Israel launched its surprise attack on Iran a week ago, saying the threat of its sworn enemy acquiring nuclear weapons had to be neutralized. While that goal hasn’t been fully met, the Islamic Republic’s military capabilities have been degraded and a number of its top generals and atomic scientists have been killed.
