President Trump To Get 'Military Options' When Deciding Iran Response

The Pentagon is presenting possible options of how to respond to what the US claims were Iranian attacks on Saudi Arabia's oil industry.

The Pentagon is presenting a broad range of "military options" to President Donald Trump, as he considers how to respond to what administration officials say was an unprecedented Iranian attack on Saudi Arabia's oil industry.

In a White House national security meeting, it is believed a list of potential air strike targets inside Iran will be shown alongside other possible responses.

President Trump will also be warned that military action against the Islamic Republic could escalate into war, according to sources.

Any decision may depend on what kind of evidence the US and Saudi investigators are able to provide to show that Iran was responsible for the attacks.

The US Secretary of State Mike Pompeo has described the attack on Saudi Arabian oil facilities as an "act of war" during a visit to Saudi Arabia to discuss the attack on the Aramco oil facility.

Meanwhile, Assistant to the Secretary of Defense for Public Affairs Jonathan Hoffman has told members of the press that the US would wait for a 'final assessment' from Saudi Arabia.

Earlier this week, the Saudi Ministry of Defence held a news conference, displaying debris from missiles and drones, claiming the wreckage on show was evidence that Iran was behind the attacks.

Iran has denied involvement and warned the US that any attack will spark an "all-out war" with immediate retaliation.

Houthi-rebels based in Yemen claimed responsibility for the attack but the US said satellite images of the damaged oil facility suggested the strikes were launched from either Iraq or Iran. 

Dr Andreas Krieg, a security expert at King's College London, told Forces News: "It seems that some of these attacks were launched from surrogates in southern Iraq rather than from Yemen. 

"The Iranians are hiding behind this plausible deniability and saying 'we had nothing to do with it', when the reality is quite clear...this technology actually comes from Iran."

US Vice President Mike Pompeo also condemned the attack.

He said Americans can be "confident" that the US is going to "defend our interest in the region" and "stand with our allies".

It is thought the US response could involve military, political and economic actions.

Airstrikes, cyber-attacks and providing additional support for Saudi Arabia are believed to be some of the military options available to President Trump.

General Joseph Dunford, chairman of the Joint Chiefs of Staff, emphasised the decision to respond should be a 'political judgement', rather than a military call: "It is my job to provide military options to the president should he decide to respond with military force," he said.

A forensic team from US Central Command is currently assessing evidence from cruise missile and drone debris, trying to determine navigational information to help attribute responsibility. 

Mr Hoffman, a spokesperson for the Pentagon, said: "All indications are we have that Iran is in some way responsible for the attack on the Saudi refineries."
