Iran threatens painful response if US renews attacks

Escalating Tensions in the Strait of Hormuz

By Humeyra Pamuk and Tala Ramadan

WASHINGTON/DUBAI, April 30 (Reuters) - Iran said on Thursday it would respond with "long and painful strikes" on U.S. positions if Washington renewed attacks and restated its claim to the Strait of Hormuz, complicating U.S. plans for a coalition to reopen the waterway.

Two months into the U.S.-Israeli war with Iran, the vital sea channel remains closed, choking off 20% of the world's oil and gas supplies. That has sent global energy prices surging and heightened concerns about the risks of an economic downturn.

Efforts to resolve the conflict have hit an impasse, with a ceasefire in place since April 8 but Iran still blocking the strait in response to a U.S. naval blockade of Iran's oil exports, Tehran's economic lifeline.

US Military and Diplomatic Maneuvers

U.S. President Donald Trump was scheduled to receive a briefing on Thursday on plans for a series of fresh military strikes to compel Iran to negotiate an end to the conflict, a U.S. official told Reuters.

Such options have long been part of U.S. planning but reports of the proposed briefing, first issued by news site Axios late on Wednesday, initially spurred big gains in oil prices, with the benchmark Brent crude contract hitting more than $126 a barrel at one point. It later slipped back to around $114.

Iran’s Response to Diplomatic Efforts

Iranian Foreign Ministry spokesman Esmaeil Baghaei said on Thursday evening that it was not reasonable to expect quick results from U.S. talks, according to the official IRNA news agency.

"Expecting to reach a result in a short time, regardless of who the mediator is, in my opinion, is not very realistic," he was quoted as saying. 

Regional Security Developments

Air defense activity was heard in some areas of Iran's capital Tehran late on Thursday, Iran's semi-official Mehr news agency reported, and the Tasnim news agency said air defences were engaging small drones and unmanned surveillance aerial vehicles.

On Thursday, the United Arab Emirates said it had banned its citizens from travelling to Iran, Lebanon and Iraq, and urged those currently in those countries to leave immediately and return home, citing regional developments.

US Domestic and International Reactions

Trump reiterated to reporters on Thursday that Iran would not be allowed to have a nuclear weapon and that the price of gasoline - a key concern for his Republican Party ahead of the November midterm elections - would "drop like a rock" as soon as the war ended.

While repeating allegations of serious rights violations by Iran, Trump said he was "OK" with it playing in the upcoming soccer World Cup in the United States, after FIFA president Gianni Infantino insisted the country would take part.

Iran Warns of 'Long and Painful Strikes'

Military Threats from Iran

A senior official of Iran's Revolutionary Guards said any new U.S. attack on Iran, even if limited, would usher in "long and painful strikes" on U.S. regional positions, while Aerospace Force Commander Majid Mousavi was quoted by Iranian media as saying: "We've seen what happened to your regional bases, we will see the same thing happen to your warships."

Control Over the Strait of Hormuz

Supreme Leader Ayatollah Mojtaba Khamenei said in a written message to Iranians that Tehran would eliminate "the enemies' abuses of the waterway" under new management of the strait, indicating that Tehran intended to maintain its hold over it.

"Foreigners who come from thousands of kilometres away ... have no place there except at the bottom of its waters," he said.

Global Economic Impact

U.N. Secretary-General Antonio Guterres warned that if the disruption caused by the closure dragged on through mid-year, global growth would fall, inflation would rise and tens of millions more people would be pushed into poverty and extreme hunger.

"The longer this vital artery is choked, the harder it will be to reverse the damage," he told reporters in New York.

US Policy and Future Prospects

War Powers and Ceasefire Status

Trump faces a formal U.S. deadline on Friday to end the war or make the case to Congress for extending it under the 1973 War Powers Resolution.

The date looks set to pass without altering the course of the conflict after a senior administration official said late on Thursday that, for the purposes of the resolution, hostilities had terminated due to the April ceasefire between Tehran and Washington.

Economic Standoff and Sanctions

Trump reiterated on Thursday that Iran's economy was "a disaster," but analysts said that if he expects Iran to blink first in a game of economic chicken, he may be waiting a while.

The conflict has aggravated Iran's dire economic problems, risking calamity after the war, but it looks able to survive a standoff in the Gulf for now, despite a U.S. blockade that has cut off energy exports.   

Range of Options and International Coalition

Military and Strategic Options

As well as blocking almost all but its own shipping through the strait during the war, Iran launched drones and missiles at Israel and at U.S. bases, infrastructure and U.S.-linked companies in Gulf states.

Axios said that another plan to be shared with Trump during the briefing involved using ground forces to take over part of the strait to reopen it to commercial shipping. Trump is also considering extending the U.S. blockade or declaring a unilateral victory, officials have said.

International Coalition Efforts

In a sign the U.S. was also envisaging a scenario where hostilities cease, a State Department cable due to be delivered orally to partner nations by May 1 invited them to ‌join a new coalition, called the Maritime Freedom Construct, to enable ​ships to navigate the strait.

France, Britain and other countries have held talks on contributing to such a coalition but said they were willing to help open the Strait only when the conflict ends.

Diplomatic Developments in the Region

Iranian Foreign Minister Abbas Araqchi said after talks with Lebanese Parliament Speaker Nabih Berri on Thursday that halting Israeli attacks on Lebanon, where a shaky ceasefire is in place, formed part of the Iran–U.S. ceasefire understanding and would remain a key issue in any future process.
