Washington, Jan 13 (AP) President Donald Trump has arrived at a delicate moment as he weighs whether to order a US military response against the Iranian government as it continues a violent crackdown on protests that have left nearly 600 dead and led to the arrests of thousands across the country.

The US president has repeatedly threatened Tehran with military action if his administration found the Islamic Republic was using deadly force against anti-government protesters.

It's a red line that Trump has said he believes Iran is “starting to cross” and has left him and his national security team weighing “very strong options.” But the US military — which Trump has warned Tehran is “locked and loaded” — appears, at least for the moment, to have been placed on standby mode as Trump ponders next steps, saying that Iranian officials want to have talks with the White House.

“What you're hearing publicly from the Iranian regime is quite different from the messages the administration is receiving privately, and I think the president has an interest in exploring those messages,” White House press secretary Karoline Leavitt told reporters Monday.

“However, with that said, the president has shown he's unafraid to use military options if and when he deems necessary, and nobody knows that better than Iran.” Hours later, Trump announced on social media that he would slap 25% tariffs on countries doing business with Tehran “effective immediately” — his first action aimed at penalising Iran for the protest crackdown, and his latest example of using tariffs as a tool to force friends and foes on the global stage to bend to his will.

China, the United Arab Emirates, Turkey, Brazil and Russia are among economies that do business with Tehran. The White House declined to offer further comment or details about the president's tariff announcement.

The White House has offered scant details on Iran's outreach for talks, but Leavitt confirmed that the president's special envoy Steve Witkoff will be a key player engaging Tehran.

Trump told reporters Sunday evening that a “meeting is being set up” with Iranian officials but cautioned that “we may have to act because of what's happening before the meeting.” “We're watching the situation very carefully,” Trump said.

Demonstrations in Iran continue, but analysts say it remains unclear just how long protesters will remain on the street.

An internet blackout imposed by Tehran makes it hard for protesters to understand just how widespread the demonstrations have become, said Vali Nasr, a State Department adviser during the early part of the Obama administration, and now professor of international affairs and Middle East studies at Johns Hopkins University.

“It makes it very difficult for news from one city or pictures from one city to incense or motivate action in another city,” Nasr said. “The protests are leaderless, they're organization-less. They are actually genuine eruptions of popular anger. And without leadership and direction and organization, such protests, not just in Iran, everywhere in the world — it's very difficult for them to sustain themselves.” Meanwhile, Trump is dealing with a series of other foreign policy emergencies around the globe.

It's been just over a week since the US military launched a successful raid to arrest Venezuela's Nicolás Maduro and remove him from power. The US continues to mass an unusually large number of troops in the Caribbean Sea.

Trump is also focused on trying to get Israel and Hamas onto the second phase of a peace deal in Gaza and broker an agreement between Russia and Ukraine to end the nearly four-year war in Eastern Europe.

But advocates urging Trump to take strong action against Iran say this moment offers an opportunity to further diminish the theocratic government that's ruled the country since the Islamic revolution in 1979.

The demonstrations are the biggest Iran has seen in years — protests spurred by the collapse of Iranian currency that have morphed into a larger test of supreme leader Ayatollah Ali Khamenei's repressive rule.

Iran, through the country's parliamentary speaker, has warned that the US military and Israel would be “legitimate targets” if Washington uses force to protect demonstrators.

Some of Trump's hawkish allies in Washington are calling on the president not to miss the opportunity to act decisively against a vulnerable Iranian government that they argue is reeling after last summer's 12-day war with Israel and battered by US strikes in June on key Iranian nuclear sites.

Senator Lindsey Graham said on social media Monday that the moment offers Trump the chance to show that he's serious about enforcing red lines.

Graham alluded to former Democratic President Barack Obama in 2012 setting a red line on the use of chemical weapons by Syria's Bashar Assad against his own people — only not to follow through with US military action after the then-Syrian leader crossed that line the following year.

“It is not enough to say we stand with the people of Iran,” Graham said. “The only right answer here is that we act decisively to protect protesters in the street — and that we're not Obama — proving to them we will not tolerate their slaughter without action.” Former Republican House Speaker Newt Gingrich, another close Trump ally, said the “goal of every Western leader should be to destroy the Iranian dictatorship at this moment of its vulnerability.” “In a few weeks either the dictatorship will be gone or the Iranian people will have been defeated and suppressed and a campaign to find the ringleaders and kill them will have begun,” Gingrich said in an X post. “There is no middle ground.” Indeed, Iranian authorities have managed to snuff out rounds of mass protests before, including the “Green Movement” following the disputed election in 2009 and the “woman, life, freedom” protests that broke out after 22-year-old Mahsa Amini died in custody of the state's morality police in 2022.

Trump and his national security team have already begun reviewing options for potential military action and he is expected to continue talks with his team this week.

Behnam Ben Taleblu, senior director of the Iran program at the Foundation for Defense of Democracies, a hawkish Washington think tank, said “there is a fast-diminishing value to official statements by the president promising to hold the regime accountable, but then staying on the sidelines.” Trump, Taleblu noted, has shown a desire to maintain “maximum flexibility rooted in unpredictability” as he deals with adversaries.

“But flexibility should not bleed into a policy of locking in or bailing out an anti-American regime which is on the ropes at home and has a bounty on the president's head abroad,” he added. (AP) SCY SCY

US response to Iran: president weighing military action while exploring Tehran talks and imposing 25% tariffs. President Donald Trump is weighing a potential military response to Iran's suppression of protests while exploring Tehran's private messages and keeping military options under review; he concurrently announced a 25% tariff on countries doing business with Tehran and designated a special envoy to engage Iranian interlocutors as the administration balances coercive measures with tentative diplomatic outreach.
