Pentagon warns of “most intense day of attacks” as US escalates pressure on Iran

The United States signalled a significant escalation in its military campaign against Iran on Tuesday, as Defence Secretary Pete Hegseth warned that the coming hours could mark the most intense wave of attacks since the conflict began.

Pentagon outlines escalation in operations
Speaking at a press conference at the Pentagon, Hegseth said the United States was preparing for a surge in military operations aimed at weakening Iran’s military capabilities and preventing further threats to US interests in the region.

“Today will be the most intense day of attacks,” Hegseth told reporters, indicating that American forces were prepared to significantly increase operational pressure on Iranian targets.

According to the defence secretary, the United States is pursuing a strategy focused on dismantling Iran’s ability to project military force, particularly through its naval assets and regional military infrastructure.

The Pentagon’s immediate objective, he said, includes neutralising Iran’s naval capacity and ensuring that Iranian forces cannot threaten American assets, personnel, or allies across the Middle East.

Goal: eliminate threat to US and allies
Hegseth emphasised that the United States intends to remove Iran’s capacity to threaten shipping routes, military installations, and regional partners.

He stated that US forces are targeting military capabilities that could be used to strike American bases or international maritime traffic.

“Our objective is clear,” Hegseth said. “We will ensure that Iran’s military cannot harm American targets.”

Naval capabilities have become a particular focus of US operations, especially given the strategic importance of waterways such as the Strait of Hormuz, through which a significant share of global energy supplies passes.

The Pentagon believes weakening Iran’s maritime forces would reduce the risk of disruptions to international shipping and energy markets.

Washington reiterates nuclear red line
During the briefing, Hegseth also reiterated Washington’s longstanding position that Iran will not be allowed to develop nuclear weapons.

“We will never allow Iran to obtain nuclear weapons,” he said, adding that the current military campaign is part of a broader effort to prevent Tehran from threatening global security.

Hegseth framed the conflict in strategic terms, arguing that the United States is acting to stop Iran from using military leverage to pressure the international community.

“We will no longer allow Iran to hold the world hostage,” he said.

The statement reflects the Biden-era and Trump-era continuity in US policy that nuclear proliferation in Iran remains a non-negotiable red line for Washington.

Uncertainty over the war’s timeline
Despite the escalation in military activity, Hegseth acknowledged that it remains unclear how long the conflict will last.

When asked whether the war was in its early stages or approaching a conclusion, he declined to give a specific assessment.

Instead, he said that determining the strategic phase of the conflict ultimately rests with President Donald Trump.

“I cannot say whether we are at the beginning, middle, or end of the war,” Hegseth told journalists.

The comment highlights the fluid and unpredictable nature of the confrontation, as both military operations and diplomatic pressures continue to evolve.

Global markets and geopolitical risks rise
The intensification of US military action is likely to increase geopolitical tensions and could have ripple effects across global energy markets and international trade routes.

Oil prices have already shown heightened volatility amid concerns that fighting could disrupt traffic through key shipping lanes in the Gulf region.

Financial markets around the world are closely monitoring developments, as investors weigh the risk of a prolonged conflict between Washington and Tehran.

For now, the Pentagon’s message is clear: the United States is preparing for a major escalation in military pressure against Iran.
