President Donald Trump has told the nation in a televised speech that the US military has nearly completed its goals in the Iran war. He vowed to strike Iran extremely hard over the next two to three weeks and finish the job very fast, without setting any timeline for ending the conflict. In his primetime address, Trump called for countries that receive oil through the Strait of Hormuz to show courage and seize the key waterway, which has been effectively closed by Iranian attacks since the conflict began. The president is grappling with rocketing gas prices and sliding personal popularity ratings as the war continues into its fifth week and US midterm elections loom in November. Wednesday night's speech did little immediately to reassure global oil markets that disruption to the Strait of Hormuz shipping route will ease anytime soon. The price of benchmark Brent crude was trading at about $100 a barrel before the president started speaking. Afterwards it rose to $105. In the 20-minute speech from the White House, Trump said the US was nearing completion of its core strategic objectives in the conflict, and had decimated Iran's navy drone and ballistic missile forces. Two-thirds of Americans believe the US should end the war quickly, even if it means not achieving Trump's goals. Concerns remain high as Iranian attacks across the region, including missile strikes in UAE and Qatar, continue.
