US-Iran tensions escalate after failed talks; US announces Strait of Hormuz blockade
Consensus Summary
On April 12, 2026, US President Donald Trump announced a naval blockade of the Strait of Hormuz following failed peace talks with Iran in Islamabad, Pakistan. The talks, attended by Iranâs Foreign Minister Abbas Araghchi and Parliamentary Speaker Mohammad Baqer Qalibaf, collapsed without a deal to end the war between the US, Israel, and Iran, which began on February 28. Trump accused Iran of 'world extortion' for its actions in the strait, a critical global shipping route carrying about 20% of the worldâs oil and LNG, and ordered the US Navy to intercept ships paying Iranian transit tolls and destroy mines. Iranâs IRGC responded by warning that military vessels approaching the strait would be considered a ceasefire breach and dealt with harshly. The blockade, set to begin at 10 AM Washington time on April 13, would allow ships traveling between non-Iranian ports to transit, though experts noted the risks of escalation. Meanwhile, a fragile ceasefire remained in place except in Lebanon, where Israel continued strikes against Hezbollah, an Iranian proxy. Trump also threatened to resume strikes on Iran, claiming he could 'finish up the little that is left of Iran' and target its energy infrastructure, while Iranâs leaders dismissed the blockade as ineffective and mocked rising US fuel prices.
