Iran Threatens Swift Action If US Fails to Fulfil Peace Deal Commitments

Escalating Tensions and Diplomatic Stalemate in the Strait of Hormuz

By Parisa Hafezi

Iran's Warning to the United States

DUBAI, Aug 17 (Reuters) - Iran will escalate tensions in the Strait of Hormuz and beyond, and launch an attack if the U.S. fails to implement an interim peace deal fully in a matter of weeks, a senior Iranian official told Reuters on Monday.

Potential Military Response

If the U.S. does not meet that deadline and diplomacy fails, Tehran would conduct a "timely and precise" military attack to break the U.S. naval blockade on the Islamic Republic, the official added.

Stalled Diplomatic Efforts

Diplomatic efforts to bring Tehran and Washington back to talks under a June agreement have stalled in recent weeks.

Positions of Iran and the United States

Iran's foreign minister has said the Strait of Hormuz will not reopen until the U.S. first returns to the deal, while the U.S. Treasury Secretary has warned of unprecedented economic isolation for Iran.

Iran's Preconditions and Regional Mediation

"Within the short period of a few weeks set by Iran, all the agreement's provisions must be implemented by the U.S. This is a precondition for further negotiations with the U.S.," the official told Reuters.

Role of Mediators

Mediators would share details of Tehran's deadline with Washington and regional states, the official added.

Preparation for Escalation

"Iranian entities must be prepared to escalate tensions in the Strait of Hormuz and wider region, as Iran will be ready to make decisions and take action on difficult decisions," the official said.

Shift in Iranian Policy

The Iranian official said Tehran was shifting its policy from defence to offence as it was losing confidence in the merits of diplomacy with Washington.

Lack of Confidence in Diplomacy

"It is a proven fact that the U.S. is not serious about a ceasefire and won't commit to any, so putting pressure on the enemy or relying on mediators in the hope of reaching a permanent ceasefire is not realistic," the official said.
