United States President Donald Trump finds himself in a bind as he seeks to end the war against Iran: he is under pressure to reopen the Strait of Hormuz and get US gasoline prices down, but at the same time faces a potential backlash from Iran hawks in his own party over any concessions to Tehran. Trump’s dilemma became clear during a week of hectic diplomacy marked by word of an emerging framework deal that, according to sources familiar with the matter, would extend a current ceasefire and release Iran’s stranglehold on the vital oil-shipping route while deferring discussions of its nuclear programme. Such an interim agreement, if approved by Trump and Iran’s rulers, would amount to the most significant step toward peace since he joined with Israel in attacking Iran on February 28, and could ease the soaring energy prices the conflict has triggered.
