• The Iran war is unpopular, but will it cost Trump the midterms? Our reporters answer your questions

Leaders in California have denounced Donald Trump as “reckless” and “deranged” after the US president suggested Iran could “take out” Los Angeles and San Diego – two liberal cities in the blue state that has been a frequent target of his administration.

At a rally in ruby red Nebraska on Monday night, Trump told supporters that he hoped to see a “tremendous victory” in the fast-approaching November midterm elections. He then suggested high prices due to the war with Iran were a “small price to pay for keeping the world safe – keeping our country safe”.
