Trump Ignored Explicit Intelligence Warnings Before Iran War, Leading to Prolonged Conflict

A detailed investigation by the Wall Street Journal reveals that just days before launching a war against Iran on February 28, 2026, President Donald Trump was explicitly warned by U.S. intelligence officials that killing Iran's Supreme Leader Ali Khamenei would not topple the regime. Instead, it would likely result in the rise of an even more militant and hardline leadership committed to accelerating Iran's nuclear weapons program.

In a critical Oval Office meeting, then-National Intelligence Director Tulsi Gabbard presented these stark assessments, cautioning that eliminating Khamenei would provoke Tehran to close the strategic Strait of Hormuz and intensify attacks on U.S. bases and forces in the region. Pentagon officials also warned of significant American casualties and ammunition depletion. Despite these warnings, Trump, persuaded by Defense Secretary Pete Hegseth and military leaders who believed Iran was at a historic low, proceeded with a military campaign initially planned to last six weeks.

The intelligence warnings aligned with longstanding public Iranian threats to shut the Strait of Hormuz in response to direct attacks, which would disrupt about 20% of global oil and gas trade and spike fuel prices. International experts had also cautioned that a broad military strike would backfire by convincing Tehran to rapidly develop nuclear weapons as a "insurance policy" against future attacks.

The reality on the ground has confirmed these predictions. Although Khamenei was killed by Israel shortly after the war began, the regime did not collapse. His son, Mojtaba Khamenei, assumed leadership, and the Revolutionary Guards strengthened their grip, continuing hostile actions such as attacks on commercial ships in the strait. Six months into the conflict, instead of a swift victory, the U.S. has suffered 18 dead, 756 wounded, damage to bases, depleted weapons and oil reserves, and approximately 3,000 Iranian fatalities. After multiple failed ceasefire attempts, Trump was forced to abandon his military plans and shift to economic sanctions and a naval blockade to try to force Iran's surrender.
