Iran offered a proposal to reopen the Strait of Hormuz and end the war with the U.S., but negotiations on removing its stockpiles of enriched uranium would be postponed under the agreement. 

Getting the removal and ending Iran's enrichment program are key aspects of Trump's war objectives. With movement toward an agreement stalled, the Iranian leadership is divided on whether to agree to Trump's terms on nuclear issues, Axios reported. 

In an interview with Fox News on Monday, Secretary of State Mark Rubio said the fractured positions among factions in the Iranian regime are a primary impediment toward successful negotiations. 

On Monday, Trump is planning to hold a Situation Room meeting on Iran where the topic of stalled negotiations and next steps will be discussed.

Trump said in an interview with Fox that Iran's petroleum infrastructure is stressed as storage runs out for its oil production, and he's hoping this may drive the Iranian leadership to the bargaining table.
