US President Donald Trump says he expected worse numbers from the stock market when he launched strikes on Iran at the end of February, reiterating that Tehran cannot posess a nuclear weapon.

“I did something that was, I don’t know, foolish, brave … I would do it again, but I thought the numbers would be much worse,” Trump says, addressing a rally in Florida.

“I thought the stock market would go down much more; I thought the oil prices would go up much more. I said, ‘But we have no choice, whether it does or doesn’t, I have to do what’s right: we can’t let them (Iran) have a nuclear weapon,” he adds.
