The administration of Donald Trump estimates that the first six days of the war against Iran cost the United States at least $11.3 billion, according to a source familiar with a recent congressional briefing.

The estimate was shared with lawmakers during a closed-door session for senators on Tuesday, as members of Congress continue pressing the administration for more details about the conflict.

Officials stressed that the figure represents only an early estimate and does not reflect the full cost of the war so far.

The number was first reported by The New York Times.

Congressional aides said the White House is expected to request additional funding soon. Some officials have suggested the request could reach $50 billion, though others believe even that figure may underestimate the potential costs.

So far, the administration has not released a public estimate of the total expense or a clear timeline for how long the conflict might continue.

Speaking during a trip to Kentucky on Wednesday, Trump said the United States had already achieved major success in the war.

“We won,” he said, while adding that American forces would remain involved until the mission is fully completed.

The military campaign began on February 28 with coordinated airstrikes carried out by the United States and Israel against targets inside Iran.

Since then, the conflict has expanded into neighboring Lebanon and has significantly disrupted global energy markets and shipping routes.

The fighting has reportedly killed around 2,000 people, the majority of them in Iran and Lebanon.

During briefings to lawmakers, administration officials said $5.6 billion worth of munitions were used in the first two days of strikes alone.

Members of Congress have expressed concern that the rapid pace of operations could significantly drain U.S. military stockpiles.

These concerns come at a time when the American defense industry is already struggling to meet high global demand for weapons and equipment.

To address supply issues, Trump recently met with executives from seven major defense contractors as the U.S. Department of Defense works to replenish depleted stockpiles.

Meanwhile, Democratic lawmakers are demanding greater transparency from the administration.

Several have called for senior officials to testify publicly under oath about the strategy behind the war, including how long the conflict might last and what plans exist for Iran once fighting ends.

Nonsense, the US is printing money as if there is no tomorrow. All those costs will be but on Iran's account by those who run the United States, the chosen people, as we know. Once the war is over, there will be (sheer) endless oil supply heading to the US in compensation of reparation payments for the (lost) war. So happened in Iraq, Libya and on all other oil fields which were attacked by the Americans.

Same with the Ukraine saga, those costs were billed (and promptly paid) to the European Union and NATO.

So, if you report anything, bring up the WHOLE picture and do not nice-paint the US as the semi-divine police force of planet Earth :-(

The 11 billion in 6 days war costs do not include the 11 military bases in middle-east destroyed or rendered inoperable and 5 US radar sites which cost $500 million each. The costs to re-build all these US assets will piled on the war costs that is if the middle-east countries will allowed themselves to host any US assets. I hope madman Trump has budgetted for this unnecessary war.

It’s an investment

As an option to being microwaved, sounds cheap to me.

How much has Iran's sponsored terrorism cost the US, over how many years. How much has Iran's oppression of the country, unwillingness to change and strong desire to acquire a formidable Nuclear Arsenal Cost.

So we've spent 50 billion, 5 percent of the 1 trillion dollar budget for the year.

I hate War just as much as most. Unfortunately, sometimes War is actually warranted. When you are NOT oppressed and suffering it is easy to Say No to helping someone. Walk a mile in those shoes, actually think and live that life for Decades and your answer may be different.

If it is war, the US Constitution grant the sole power to formally declare war. If it is not war, the military actions will need justifications to launch an attack. So far, TRump struggles to explain and lied about the reasons. The US public which normally support US military excursions in the past are firmly against the attack on Iran. Their perception is that Israel lead US into this conflict and it is unnecessary. Many analysts say the attacks against Iran appear to breach UN Charter's prohibition on aggression. Bottom line, the war is high questionable and doesn't have any legitimate reasons and war costs were spent unnecessarily and will affact the economy and burden the people.

And, once again, the US is squandering vast amounts of money it doesn't have, going deeper into endless, bottomless debt, on yet another useless, unjustified war, while China is wisely spending its money at home. Didn't learn from Vietnam. Didn't learn from Afghanistan. Didn't learn from Iraq. Slow learner.

They needed to think harder about this moment when they decided to support ayatollahs 47 years ago and removing king (he was accused by humans right) of Iran by a revolution set up.
