MANAMA: The United States warned on Saturday it was capable of deploying "overwhelming force" in the Middle East as it faced questions about its willingness to use its military power in the region, reports AFP.
Defense Secretary Lloyd Austin told the Manama Dialogue in Bahrain's capital that all options would be open if diplomacy fails to halt Iran's nuclear programme, but he was also forced to rebut claims the US has become reluctant to use force.
"The United States of America maintains the right to defend itself. And we will defend ourselves and our interests, no matter what, at the time and place of our choosing," he replied.
"And let no country, let no individual be mistaken about that. We are committed to defending ourselves and our interests and that includes our partners as well," said Austin.
"And we're also committed to not allowing Iran to get a nuclear weapon."
Iran and world powers are set for talks on November 29 aimed at reviving an accord that placed restrictions on its nuclear programme in exchange for sanctions relief. Tehran has always denied it is seeking nuclear weapons.
Austin said Washington's major goal was to strengthen its "unmatched" alliances in the Middle East, but said military force remained an option with tens of thousands of its troops stationed in the region.
This month, Iraq's prime minister escaped an assassination attempt two days after security forces clashed with supporters of Iran-backed parties that lost support in recent elections.
On Saturday, Iran said it had seized a foreign boat smuggling diesel in the oil-rich Gulf.
Since February, Iran and Israel have been engaged in a "shadow war" in which vessels linked to each country have come under attack in waters around the Gulf.
The US and Israel accuse Iran of using drones and missiles to destabilise the region.
In brief remarks to the forum, senior Saudi figure Turki bin Faisal Al Saud called for "demonstrative action" in the region, including the "total enforcement" of the arms embargo on Yemen's Iran-supported Huthi rebels, who are fighting a Saudi-led coalition.
Austin said that "America's commitment to security in the Middle East is strong and sure."
"Ultimately, our mission is to support diplomacy and to deter conflict and to defend the United States and our vital interests," he said. "If we're forced to turn back aggression, we will win and we will win decisively."
Austin's visit comes days before Iran returns to talks with world powers on resuming a nuclear deal which has been stalled since 2018, when former US president Donald Trump walked away.
On Friday, US special envoy Robert Malley told the conference that time was running out to return to the deal if Iran continues to make "advances" in its nuclear programme.
