Trump says he favors a nuclear deal with Iran but won’t hesitate to take military action if talks collapse, insisting he won’t be dragged into war by Israel — but might enter one by choice.

The president said he would be “leading the pack” against Iran if it did not agree to a nuclear deal, but he said he was open to meeting Iranian leaders.

U.S. President Donald Trump this week said he is open to meeting Iran's supreme leader or president and that he thinks the two countries will strike a new deal on Tehran's disputed nuclear programme.
