US Secretary of State Antony Blinken says Iran's responses to our willingness to return to nuclear talks have not been “encouraging” despite the fact that "time is running short" for Tehran.

US President Joe Biden's administration has hinted it could use force if diplomacy fails on Iran's nuclear program, rallying more closely than ever behind warnings by Israel.

As negotiations with Iran remain at a standstill, US Secretary of State Antony Blinken held three-way talks with the top diplomats of Israel and the United Arab Emirates, two US allies which established relations last year amid shared concerns about Tehran.

Blinken renewed Biden's offer to re-enter a 2015 nuclear agreement, trashed by former president Donald Trump, in which Iran drastically scaled back nuclear activity in return for unfulfilled promises of sanctions relief.

"We're united in the proposition that Iran cannot be allowed to acquire a nuclear weapon," Blinken told a joint news conference in Washington. 

"We believe that the diplomatic path is the most effective way to ensure that that doesn't happen," he said.

But he said Iran has already had nine months since Biden's election to demonstrate its commitment.

"With every passing day, and Iran's refusal to engage in good faith, the runway gets short," Blinken said.

"We are prepared to turn to other options if Iran doesn't change course," he warned.

He did not elaborate – but Israeli Foreign Minister Yair Lapid, without being contradicted, said of Blinken's comments, "I think everybody understands – here in Israel and in the Emirates and in Tehran – what it is that we mean."

Lapid earlier said that both he and Blinken, as sons of Holocaust survivors, "know there are moments when nations must use force to protect the world from evil."

"If a terror regime is going to acquire a nuclear weapon, we must act. We must make clear the civilized world won't allow it," Lapid said.

"Israel reserves the right to act at any given moment in any way. That is not only our right; it is also our responsibility."

US 'realistic' on future

Iran and the United States held six rounds of indirect talks this year on returning to compliance, with a European Union mediator shuttling between the two sides in Vienna hotel rooms.

Talks were last held in June before the inauguration of a new hardline Iranian government that took over from President Hassan Rouhani, who had sought a better relationship with the West.

Rob Malley, the US negotiator, rejected suggestions that the talks had failed to make progress but he said the United States was still waiting for Iran to move forward.

"We feel like coming back would still be the best outcome but we're realistic," Malley said at an event at the Carnegie Endowment for International Peace.

"We know that there's at least a good possibility that Iran is going to choose a different path and we need to coordinate with Israel and with our other partners in the region," Malley said.

After taking part in the talks with Israel and the UAE, Malley said he would head in the coming days to the UAE as well as Saudi Arabia and Qatar.

Iran denies it is seeking a nuclear weapon, which the clerical state argues is religiously forbidden.

But Tehran believes it needs to defend itself in a hostile neighborhood, with memories still vivid of the brutal 1980-88 war launched by Iraqi dictator Saddam Hussein with backing from the West.

Iran has said repeatedly that it is ready to resume talks "soon" but no date has yet been announced.

Enrique Mora, the EU envoy in charge of reviving the troubled deal, plans to visit Tehran on Thursday in a new bid for progress.

Few experts expect Biden to favor military action against Iran, a more formidable foe than Afghanistan's Taliban or Saddam's Iraq, after Biden made the high-stakes decision to leave Afghanistan.

But Israel has already been engaged in a shadow war with Tehran, targeting Iranian military sites in ally Syria and carrying out a sabotage campaign inside Iran against its nuclear program.

Former prime minister Benjamin Netanyahu vehemently opposed the 2015 nuclear accord and openly campaigned against then president Barack Obama's diplomacy.
