Iran has put forward a seven-day timetable to reopen the strait of Hormuz and begin talks on its nuclear programme, according to the Guardian. The proposal has been pitched as a deal that could rapidly extricate President Donald Trump from a political crisis, but it requires the US president to make difficult concessions.

The Guardian reports that with five days left before the proposed reopening of the strait, Trump faces a series of demanding conditions. The reopening itself is expected to relieve pressure on global energy markets, a factor with implications ahead of the US midterm elections.

Among the terms, Trump would need to lift Iranian asset freezes and permit Iran to export its oil, according to the report. These steps would mark a significant shift in US policy toward Tehran.

Perhaps the most difficult condition, the Guardian notes, would be for Trump to order Israeli Prime Minister Benjamin Netanyahu to end Israel’s attacks on Hezbollah in Lebanon, thereby achieving what has been described as a “ceasefire on all fronts.”

The framing of the deal ties Iran’s nuclear diplomacy directly to the situation in Lebanon and to global energy markets, placing Trump in a position where any decision carries both foreign policy and domestic political consequences.

The proposal arrives against the backdrop of the approaching US midterm elections, adding a layer of political calculation to the choices facing the White House, according to the Guardian’s reporting.
