Donald Trump believes that the defeat of the Republicans in the US midterm elections was due "in large part" to the war with Iran and the increase in gas prices. "I think that's true to a large extent because it drove gasoline up in the short term, and that's probably true," he said. However, he stressed that he believed the war was worth starting. "But at the same time, if I had to do it again, I would have to do it again because long term, that's the only answer. You cannot allow Iran to have nuclear weapons," Trump said.
