Iran, under pressure, signals readiness to escalate war with U.S.

Iran Warns of Escalation After U.S. Warship Attacks

Iranian leaders signaled readiness this week to escalate conflict with the United States after Tehran struck American warships for the first time in the ongoing war.

On Saturday, Iran said its ballistic missiles had attacked two U.S. military vessels in the Persian Gulf for the first time. American forces retaliated by striking three Iranian oil tankers, and a U.S. official confirmed another strike against tankers hours later.

A day later, Mohammad Bagher Qalibaf, Iran's parliament speaker and lead negotiator, declared before lawmakers that the era of proportionate responses to U.S. attacks was over.

Mohsen Rezaei, Iran's security chief, announced plans to impose a restricted shipping zone in the Gulf beyond the Strait of Hormuz. Iranian officials warned that any escalation of the U.S. blockade would draw a military response, signaling a more aggressive posture.

President Donald Trump has so far rejected negotiations and is maintaining a strategy of attrition through an economic blockade, despite repeated Iranian signals of openness to talks.

Economic Blockade Deepens Iran's Domestic Crisis

The U.S. naval blockade has for months prevented Tehran from exporting much of its oil, deepening a longstanding economic crisis. On Tuesday, the government raised gasoline prices because of fuel shortages, a move expected to unsettle a country facing high inflation.

International oil prices have climbed as a result, with Brent crude, the global benchmark, surpassing $100 per barrel on Wednesday for the first time since late July.

Shipping through the Strait of Hormuz has fallen below two million barrels a day because tankers face attacks from Iranian forces. That volume had reached about nine million barrels per day before the latest escalation, according to data reported by Reuters.

Meanwhile, U.S. naval escorts have enabled a small trickle of tankers through the waterway, undercutting Iran's closure as global oil prices remain at sharply elevated levels.

For Tehran, the U.S.-led blockade and economic pressure have become a domestic security risk that is prompting leaders to adopt a far more aggressive military posture.

Diplomacy Stalls Amid Spreading Regional Attacks

President Masoud Pezeshkian and other senior Iranian officials have once again said they remain willing to return to the fragile memorandum that halted the war in April.

Although the memorandum's 60-day deadline expired on Aug. 17, no formal negotiations have resumed despite repeated signals from senior Iranian officials about returning to the talks.

Tehran has demanded broad sanctions relief, access to frozen assets, and an end to the U.S. naval blockade of Iranian ports. Washington insists Tehran accept strict limits on its nuclear program and guarantee unrestricted commercial passage through the Strait of Hormuz.

Meanwhile, Iran's Houthi militia allies in Yemen launched new attacks on southern Saudi Arabia on Tuesday, wounding dozens and prompting Riyadh to vow retaliation, Saudi officials said.

Saudi Arabia and the United States earlier jointly bombed Iran-backed Iraqi militias blamed for drone attacks on Saudi oil facilities. Regional officials told the Associated Press that Houthi emissaries worked in an Iraqi-run operations room, revealing a new level of coordination.
