Both countries have been in the spotlight in recent weeks following a serious commentary by Donald Trump and Iranian officials, including Supreme Leader Ali Khamenei. Patrick Shanahan, the acting Secretary of Defense, has tried to calm relations between states by insisting that every possible attack on Iran is "put on hold". The US recently warned of a potential threat from the country, with US President Donald Trump tweeting, "If Iran wants to fight, it will be Iran's official end."
Always insisting that the US does not want to be involved in a conflict with the Islamic Republic, Mr. Shanahan has said that the US attitude is for deterrence.
Shanahan added: "I just hope Iran listens.
"I think our steps were very careful and we have suspended the potential for attacking Americans, which is extremely important.
"I would say that we are in a period where the threat remains high and it is our job to ensure that there is no miscalculation by the Iranians.

"We are in the region to tackle many things, but it is not to go to war with Iran."
Tensions between the two countries intensified after the announcement that the US would send a strike force to the region.
Continuing that trend, the US officials also pulled non-essential personnel out of the country amidst an alleged threat to pro-Iranian forces.
The US has recently withdrawn exemptions that allowed certain countries to purchase crucial goods from Iran earlier this month.

Trump also ended the nuclear pact with the country last year.
Last week four oil tankers were attacked in the Gulf of Oman.
US investigators believe that Iran or pro-Iranian groups may be responsible for the attack, although the country strongly denies the allegations.
Speaking about the tensions, British Foreign Minister Jeremy Hunt warned: "I would say to the Iranians: don't underestimate the intention on the American side.
"They don't want a war with Iran.
"But if American interests are attacked, they will take revenge."
