Reuters - Britain told Iran on Monday not to underestimate the resolve of the United States, warning that if American interests were attacked then the administration of President Donald Trump would retaliate.

�I would say to the Iranians: Do not underestimate the resolve on the U.S. side,� Foreign Secretary Jeremy Hunt told reporters on the sidelines of the World Health Assembly in Geneva.

�They don�t want a war with Iran. But if American interests are attacked, they will retaliate. And that is something that the Iranians needs to think about very, very carefully.�
