US defense chief warns Iran against underestimating American military resolve

The United States Secretary of Defense, Pete Hegseth, has cautioned Iran against misjudging Washington's capacity to sustain military operations. Hegseth made these remarks during the inaugural Americas Counter Cartel Conference, held at the US Southern Command headquarters in Doral, Florida, on March 5, 2026. The event was attended by regional defense and security leaders.

During his address, Hegseth referenced the ongoing tensions between the United States and Iran, emphasizing that any miscalculation regarding US military endurance could have significant consequences. He highlighted the importance of the joint security agreement and reiterated the United States' commitment to its defense partnerships in the region.

Meanwhile, Iranian officials have responded with strong statements. According to reports, Iranian representative Araghchi declared that Iran is prepared and "waiting" for any potential US invasion. This statement follows recent developments in the region, including a reported strike in Tehran that has been linked to a blaze at a refinery in Bahrain. Sources indicate that the incident has heightened tensions between the two countries.

While details surrounding the refinery fire in Bahrain remain limited, the blaze was sparked by a strike originating from Tehran. However, there has been no official confirmation regarding the direct cause of the incident.

The exchange of warnings and statements comes amid a period of increased scrutiny on security and defense matters in the region. Both US and Iranian officials have signaled their respective positions, with the United States underscoring its military capabilities and Iran asserting its readiness for confrontation.

Sources note that the situation remains fluid, with both sides closely monitoring developments. Further official statements are anticipated as events unfold.
