Trump’s Iran war already costs more than Bush’s Iraq opening

President Donald Trump spent two decades attacking the Iraq War as a catastrophic mistake. In 2003, as a developer, he called the invasion a blunder. In his 2016 campaign, he hammered former President George W. Bush relentlessly, calling it “a disaster for this country” and “one of the worst decisions ever made.”

As a candidate, Trump consistently promised to end the endless Middle East wars, not start new ones. Yet three weeks into the U.S. campaign in Iran, he is asking for more money up front than Bush did for what became a $2 to $3 trillion nightmare.

To fund the next phase of Operation Epic Fury, the Pentagon is requesting $200 billion to continue the campaign, according to a senior administration official who spoke with The Washington Post. That figure is roughly $67 billion more than Bush asked Congress for when the Iraq invasion began on March 19, 2003.

Adjusted for inflation, Bush’s $74.7 billion request would be worth about $133 billion today. Trump’s Iran request, designed for an air campaign with no ground troops, already exceeds it. The cost curve shows how modern warfare expenses have shifted and how quickly even limited operations expand.

The Modern Warfare Paradox

While the United States has avoided the massive bill for feeding and housing thousands of troops as it did in Iraq, it has replaced those costs with the even higher price of high-tech warfare.

Bush’s $74.7 billion was designed to fund roughly five months of ground operations involving 150,000-plus troops, armored divisions, and a 49-nation coalition. Congress ultimately approved $79 billion on April 12, 2003. By September, Bush was back requesting another $87 billion.

Trump’s $200 billion request addresses fundamentally different needs. Defense Secretary Pete Hegseth stated on March 19 that the money would fund operations already conducted, potential future operations, and critically, munitions replenishment. The U.S. isn’t staging a ground invasion. It’s conducting an air and naval campaign so intensive that it has burned through years’ worth of precision-guided weapons in weeks.

After striking more than 7,000 targets across Iran in three weeks, the U.S. has depleted its inventory of advanced munitions at an unprecedented rate. Tomahawk cruise missiles cost around $3.5 million each. JDAM-guided bombs, which cost less than $100,000, deliver the same 1,000-pound payload with equal accuracy. Both have been essential to the campaign, but in the early days, reliance was heavy on the expensive standoff weapons.

By the fourth day of Operation Epic Fury, the U.S. military had achieved air dominance. Commanders switched to cheaper, shorter-range munitions like JDAMs, cluster munitions, and unguided weapons—reserves that were far more abundant in existing stockpiles. The Pentagon had struck over 2,500 targets by day six, but the switch to cheaper munitions led to a sharp decline in daily spending after the initial blitz.

Total war costs reached $16.5 billion by day twelve, up 46 percent from day six’s $11.3 billion, according to the Center for Strategic and International Studies. The daily burn rate had dropped substantially. Mark Cancian, a senior adviser at CSIS, told Newsweek that the timing of the request is unusual.

“It’s uncommon for a supplemental to be proposed before the conflict ends, unless the conflict is expected to go on for a long time. I don’t think that’s the situation here,” he said.

Structural Differences

The most important structural difference remains scope. Iraq was a full-scale ground invasion with 150,000-plus troops, followed by years of occupation and counterinsurgency fighting. Operation Epic Fury is an air and naval campaign with no ground forces deployed and no Phase IV stabilization plan. A RAND study estimated a ground invasion of Iran would require 500,000 to 1,000,000 troops—forces the U.S. does not have available and could not sustain politically.

Iran’s geography is fundamentally more challenging than Iraq’s. At 1.65 million square kilometers, Iran is roughly four times the size of Iraq and is covered by mountains exceeding 4,400 meters. Iran’s population of approximately 90 million dwarfs Iraq’s 25 million in 2003. Iran’s military, ranked 16th globally, possesses dispersed underground facilities, advanced air defenses, and a proxy network spanning multiple countries.

Yet the $200 billion request, covering just weeks of air operations plus munitions replenishment, already exceeds what Bush spent annually at the peak of the Iraq surge with 170,000 troops deployed. An air campaign requires different infrastructure and logistics than a ground occupation, but the upfront costs are steeper.

From Trump to Defense Secretary Pete Hegseth, White House officials have offered shifting explanations for the campaign. Early statements focused on destroying Iran’s nuclear and ballistic missile capabilities. Within days, the targets expanded to Iran’s navy. Then came talk of severing proxy networks across the region. By the second week, officials were discussing strikes on Iranian oil infrastructure.

Hegseth explained the difference in the press conference Thursday, stating that most of the $200 billion is not the cost of the war but the cost of building U.S. military capability.

“Hear it from me, one of hundreds of thousands who fought in Iraq and Afghanistan, who watched previous [administrations] squander American credibility — this is not those wars,” he said.

However, for many historians and military experts this ambiguity mirrors Iraq’s opening weeks, when stated war aims shifted constantly. In March 2003, the stated mission was to disarm weapons of mass destruction. By April, it had shifted to regime change. By summer, to stabilization and reconstruction.

Bush officials systematically underestimated Iraq’s cost. Pre-war, OMB Director Mitch Daniels pegged the war at $50-60 billion. Defense Secretary Donald Rumsfeld dismissed higher estimates as “baloney.” White House economic adviser Larry Lindsey’s projection of $100-200 billion was leaked to The Wall Street Journal in 2002, and he was eventually pushed out for his candor.

Every estimate proved spectacularly wrong. The Costs of War Project at Brown University calculated direct costs at $1.79 trillion through 2023, rising to $2.89 trillion when projected veterans’ care through 2050 is included.

The $200 billion request requires 60 votes in the Senate, with Democratic support appearing highly unlikely. Bush faced no such obstacle. When he requested funding for Iraq in spring 2003, he was riding a wave of post-9/11 approval. Congress approved $79 billion with little resistance.

Trump is asking for far more money for a more limited operation, with far less public support.
