Dallas: US President Donald Trump said on Thursday that he did not regret going to war against Iran despite the impact it may have on the November US midterm elections.

During an interview with Fox News host Laura Ingraham, he dismissed suggestions that some of his supporters were upset and demoralised about the war. Trump reiterated his view that the war will end immediately after the midterm election.

The rise in oil and gas prices due to the US-Israeli war on Iran has become a major issue for Republicans in the lead-up to the elections.

The US and Israel attacked Iran on February 28, and Iran responded with its own strikes on Israel and Gulf states that host US bases. Trump has cited weakening Iran's nuclear capabilities as one of his war objectives. Iran does not have nuclear weapons and says its uranium enrichment programme is for peaceful purposes; meanwhile, the US is nuclear-armed.
