A Senator close to Trump, Lindsey Graham, on Tuesday 21 May warned Iran of an "overwhelming military response" for any actions against US interests.
Sen. Lindsey Graham said that the US should attack Iran if Tehran followed through on threats against Americans or America’ s interests, according to AFP.
“The fault lies with the Iranians, not the United States or any other nation. If the Iranian threats against American personnel and interests are activated we must deliver an overwhelming military response,” Graham tweeted. “Stand firm Mr. President.”
Relations between Washington and Tehran plummeted a year ago when Trump pulled out of a landmark 2015 nuclear deal with Iran and imposed tough sanctions.
Iranian officials have repeatedly slammed the unilateral US sanctions as "economic terrorism," saying that they have impeded the flow of essential goods.
Tensions have risen further this month with Washington announcing more economic measures against Tehran, before deploying a carrier group and B-52 bombers to the Gulf over unspecified alleged Iranian "threats".
The Trump administration last week ordered non-essential diplomatic staff out of Iraq, citing the danger posed by Iranian-backed Iraqi armed groups.
