ahead of a Nato summit in Turkey, the president said US negotiators could continue talks "if they want" but said he saw it as "a waste of time". Oil prices jumped after Trump's comments, although are still well below the highs seen during the full closure of the Strait of Hormuz. Tuesday night into Wednesday saw the worst trading of strikes between the US and Iran since they signed an interim deal in June that called for an end to the conflict and safe passage of vessels through the strait. "I think it's over. I don't want to deal with them anymore they're scum ... they're led by sick people and they're vicious, violent people”, Trump said.  "We make a deal. They [Iran] go outside, talk to the press, they say 'we never even talked about it'. There's something wrong with them. They're cuckoo. As far as I'm concerned, it's over." (BBC)
