The United States, led by Joe Biden, announced Wednesday a comprehensive change of US policy in the Middle East, including a "review" of military support to the Gulf states. 

It was also announced that the possible resumption of dialogue with Iran "will take some time."

The future of the Iran nuclear deal that Donald Trump withdrew Washington from looks set to be one of the most urgent priorities on the international stage.

But US Secretary of State Anthony Blinken, a day after taking office, tempered the rush. In his first press conference, he said, "President Biden made it clear that if Iran once again fulfills all of its obligations...the United States will do the same."

He added that Iran "has stopped fulfilling its obligations on several fronts. It will take some time if it takes this decision, to get back on the right track, and it will take time until we can assess whether it is fulfilling its obligations. We are still very far from that."

But the negotiations will likely be difficult because Iran is asking for the opposite, and it wants Washington to take the first step by lifting US sanctions before anything else.

Anthony Blinken did not clarify how he intends to solve this problem. Wednesday, he met his French, British and German counterparts who are very attached to the Iranian agreement.

Blinken's comments came as Russia and Iran called Tuesday for the United States to save the nuclear deal so that Iran respects its obligations. Russian Foreign Minister Sergey Lavrov said upon his meeting with his Iranian counterpart, Mohammad Javad Zarif, "The very issue at stake is salvaging [the agreement], and we, like Iran, hope to return to its full and complete implementation."

Iran mentioned Biden just two days after he assumed his presidential duties, writing what it considers to be the requirements of saving the nuclear deal.

In an article published in the American Foreign Affairs magazine, Zarif said, "The new government in Washington must make a basic choice: adopt the failed Trump administration policies and continue along the path of contempt for international cooperation and law ... Or Biden can choose a better path by ending the failed, maximum pressure policies adopted by Trump and a return to the agreement abandoned by his predecessor. "

The agreement concluded in 2015 is supposed to prevent Iran from acquiring an atomic bomb.

But in 2018, the former Republican president closed the door, believing that the agreement was not sufficient to stop the "destabilizing activities" of the Islamic Republic in the Middle East. 

But Biden believes that this agreement must be saved first of all to avoid the emergence of a nuclear Iran.

- 'The worst humanitarian crisis' -

Blinken reiterated that "then we will use that as a starting point to build, with our allies and partners, what we called a more permanent and robust agreement, to deal with many other issues that pose a major problem in the relationship with Iran," without adding any details. 

But Blinken said, "But we are far from that."

At the same time, the State Department launched a review of the previous government's controversial recent decisions.

The first result of Washington was suspending "ongoing" arms sales until "a re-examination" to ensure that they achieve "strategic objectives," according to the US State Department on Wednesday. This decision including freezing the sale of ammunition to Saudi Arabia and F-35 fighter jets to the United Arab Emirates.

Riyadh, with the support of Abu Dhabi, is leading a military alliance with the Yemeni government in the conflict between it and the Iranian-backed Houthi rebels.

Blinken pledged last week to "end" US support for this coalition, which is accused of committing many grave mistakes against Yemeni civilians. Wednesday, he said, this alliance "has contributed to what is often considered the world's worst humanitarian crisis today."

At the same time, he stressed a "very urgent" review of the decision to include the Houthis on the US list of "terrorist organizations," which faced criticism from all sides because it threatens to impede the delivery of humanitarian aid to large areas controlled by the rebels.

The suspension of the UAE's sale of F-35s was a symbolic development because it was decided in the fall, after years of rejection, in exchange for recognition of the Israeli Occupation. 

Blinken welcomed the historic Trump-brokered normalization of relations with the Hebrew state and the UAE, Bahrain, Morcco and Sudan, but indicated that he had already begun to "consider" the "commitments" made by Washington in order to successfully ensure their brokerage. 

The US secretary did not respond to two questions about the reversal of the decision to sell F-35s or the recognition of Moroccan sovereignty over Western Sahara.
