A senior Iranian official warned that any attack by the U.S. would be treated as an "all-out war," ahead of a U.S. military buildup in West Asia.

The official stated Iran's military is on high alert and ready for the worst-case scenario. This comes after U.S. President Donald Trump said the U.S.

had an "armada" heading toward Iran. The Iranian official warned that if the U.S. violates Iran's sovereignty, they will respond.

The U.S. military has periodically increased forces in West Asia during times of heightened tensions. Analysts suggest the military buildup could give Trump the option to carry out strikes.

Background

The relationship between Iran and the United States has been fraught with tension since the 1979 Iranian Revolution, which ousted the U.S.-backed Shah and established an Islamic Republic. The hostage crisis at the U.S. embassy in Tehran further deteriorated relations.

The U.S. has since imposed various sanctions on Iran, particularly concerning its nuclear program. Key events shaping this relationship include the Iran-Iraq War (1980-1988), where the U.S.

indirectly supported Iraq, and the more recent U.S. withdrawal from the Joint Comprehensive Plan of Action (JCPOA), also known as the Iran nuclear deal, in 2018. This withdrawal and subsequent re-imposition of sanctions have significantly escalated tensions.

Latest Developments

In recent years, tensions have been exacerbated by attacks on oil tankers in the Persian Gulf, attributed by the U.S. to Iran, and Iran's increasing enrichment of uranium beyond the limits set by the JCPOA. The assassination of Iranian General Qassem Soleimani in 2020 further escalated the situation.

Negotiations to revive the JCPOA have been ongoing, but progress has been slow and uncertain. The current military buildup reflects a continuation of this pattern of heightened tensions and brinkmanship, with both sides seeking to deter the other from further escalation.
