Islamabad Talks

The United States and Iran engaged in marathon peace talks in Islamabad, marking the highest-level diplomatic engagement in decades.

Vice President JD Vance led the U.S. delegation.

After 21 hours, the talks ended without a breakthrough.

Vance said the Iranians moved but not enough to satisfy Washington.

Core sticking points included Iran's nuclear program and the Strait of Hormuz.

Iranian Foreign Minister Araghchi said they were inches away when they encountered maximalism and blockade.

Nuclear and Hormuz

The nuclear program remained the central obstacle.

Iran had proposed suspending uranium enrichment for five years, but Trump rejected that.

Vance tied signing a major deal to Tehran renouncing its pursuit of a nuclear weapon.

The Strait of Hormuz was another flashpoint.

The U.S. naval blockade began Monday, with Trump declaring it effective immediately.

Iran's IRGC warned it would consider the blockade a cease-fire violation.

Aftermath and Next Steps

Vance returned without a deal but left the door open.
