Today, Tuesday, negotiations on the Iranian nuclear file will resume, which the parties hope to be fruitful this time, and for each party to seize the current opportunity.
According to a source from Tehran, the Iranian team went to Vienna with a clear agenda, and that Tehran had made its political decision regarding the Vienna talks, and therefore the Western side should make its final decision and not waste the current opportunity, as he put it.
The source added that the failure to take a political decision on the American side is the main obstacle so far, and it should worry about wasting this opportunity, according to what he said.
A source familiar with the talks told Agence France-Presse that the delegations returned to the Austrian capital, Vienna, and are expected to arrive in the afternoon at the luxurious Coburg Palace, where the talks are taking place.
Washington - which is not directly involved in the negotiations - did not hide its enthusiasm on Monday;
"Despite the progress made," a US State Department spokesman told AFP, "the talks have reached a stage where concluding an agreement has become urgent."
"There are features on the horizon of an agreement that addresses the fundamental concerns of all parties. But if it is not concluded in the coming weeks, Iran's continued nuclear progress will make our return to the Comprehensive Plan of Action (the 2015 framework agreement) impossible," he said.
In an interview with the "Washington Post" and published on its website Monday, German Chancellor Olaf Scholz spoke of a "decisive moment".
"We sent a clear message" to Iran that "the time has come to make decisions, not procrastinate," Schultz said, expressing hope that "the Iranians seize this opportunity."
The negotiators separated at the end of last January on a call to take "political decisions" after the progress made during the beginning of this year, which allowed a way out of a long-standing deadlock.
The talks began in the spring of 2021 between Iran and the countries that are still party to the agreement - namely Germany, China, France, the United Kingdom and Russia - while the Americans participate in an indirect way.
On the other hand, a group of 33 Republican members of the US Senate notified President Joe Biden - yesterday, Monday - that they will work to block any new nuclear agreement with Iran, if his government does not allow Congress to review and vote on its terms.
He told senators led by Ted Cruz, a long-time opponent of the 2015 Iran nuclear deal, that they would use "the full range of options and influence available to them" to ensure his government abides by US laws governing any new deal with Iran.
The Biden administration is seeking to revive the agreement that lifted sanctions on Tehran in exchange for restrictions on its nuclear activities, before former US President Donald Trump announced his country's withdrawal from it in 2018.
Cruz and other senior Republican senators told Biden that implementation of any new agreement "will be hampered significantly, if not permanently," if it does not meet legal obligations aimed at ensuring congressional oversight of amendments or changes to the 2015 nuclear deal. 2015.
