The US-Israeli war on Iran, which has killed about 2,000 people and displaced about 800,000 in Lebanon, is estimated to have cost the United States at least $11.3bn in the first six days of the conflict, according to a source familiar with the matter. This figure does not include the entire cost of the war, but was provided to lawmakers for more information. The White House is expected to submit a request to Congress for additional funding for the war. The administration has not yet provided a public assessment of the cost or a clear estimate of its expected duration. The conflict has raised concerns about depleting US military stocks at a time when the defence industry is struggling to meet demand.
