A classified document that was leaked to the Washington Post on Monday shows that the four highest‑ranking U.S. commanders responsible for operations in Europe, the Pacific, South America and the Navy’s top admiral have formally informed Secretary of Defense Pete Hegseth that the ongoing war in Iran has depleted the forces they need to respond to other potential conflicts.

The document is a “non‑concur” notice issued in response to the August 14 edition of the Secretary of Defense Orders Book (SDOB). The SDOB, produced twice a month, lists the worldwide availability of warships, aircraft, personnel and weapons systems and is used by the secretary to set the president’s priorities for the armed forces. The non‑concur notes indicate that the commanders’ current inventories fall short of the numbers required to meet those priorities.

According to the Post, the four commanders—who oversee U.S. forces in Europe, the Pacific, South America and the Navy—were unable to meet the SDOB’s requirements because a large portion of their aircraft, ships and munitions had been redirected to the Middle East. The notice was filed on the same day that the SDOB was released, suggesting a direct link between the war effort and the reported shortfall.

The SDOB also specifies that roughly 50,000 U.S. troops and much of their equipment must remain in the Middle East through September and, in some cases, into the following year. The non‑concur statements therefore warn that the U.S. military’s readiness to respond to other crises—such as a potential Chinese assault on Taiwan, a North Korean incursion into South Korea, a Russian move in the Baltics or an attack on Israel—cannot be sustained if the Iran war continues.

The Washington Post report follows a series of public statements that have highlighted the war’s impact on U.S. forces. In the first six months of the conflict, the U.S. has reportedly used more than half of its cruise missiles and advanced air‑defense missiles. The Pentagon has moved a THAAD missile system from South Korea to the Persian Gulf and relocated the USS George Washington and its escort warships from Japan to the Gulf, removing the Navy’s only aircraft carrier from the Pacific.

The Post article also places the non‑concur notices in the broader context of Secretary Hegseth’s tenure. Since taking office in 2025, Hegseth has been criticized for a range of actions, including blocking the promotion of at least 45 officers, reversing the services’ peer‑review boards and terminating programs that supported officer development. The Washington Post notes that half of the officers whose promotions were blocked were Black or female, a fact that has drawn attention amid Hegseth’s public statements questioning the role of diversity and inclusion in the military.

Hegseth’s leadership style has also been described as “quirky” by some observers. In April, he dismissed an Army unit focused on drone warfare and ordered it to return to a “core” infantry mission, despite drone operations now being a core capability. He has also ended programs that sent officers to study history and strategy at universities, labeling them “woke.” In addition, he has announced a policy to test troops for testosterone levels, a move that has raised concerns about the impact on readiness.

The non‑concur notices are the first time that four senior commanders have filed such statements simultaneously while a war is underway. According to the Post, past commanders have occasionally filed warnings about readiness, but the scale and timing of this notice are unprecedented.

The Washington Post report comes at a time when U.S. and Iranian forces have resumed missile exchanges after a month of relative calm. The war, which began on February 28, 2026, has already cost the U.S. an estimated $113.3 billion and has prompted the Trump administration to request $1.5 trillion for the Pentagon in the next fiscal year.

The Pentagon has not yet issued a formal response to the non‑concur notices. Hegseth’s office has not released any statements regarding the document. The Department of Defense has said it is reviewing the situation.

The reports raise questions about how the U.S. will balance its commitments in the Middle East with its obligations to allies in Europe, the Pacific and South America. The non‑concur notices suggest that the war may force a re‑allocation of resources that could leave other regions vulnerable.

The situation remains fluid. The next SDOB release will likely reflect any adjustments made to the force structure. The Pentagon’s ongoing assessment of the war’s impact on readiness will be closely watched by allies and adversaries alike.

The Washington Post has not confirmed whether the document was obtained through a leak or a whistleblower. No official statements from the Department of Defense or the White House have been made public.

The report underscores the broader debate over the sustainability of the U.S. war effort in Iran and the potential consequences for global security. The Department of Defense will likely need to address the readiness gaps identified by the senior commanders before the next SDOB cycle.

The Washington Post will continue to monitor developments related to the non‑concur notices and the broader implications of the Iran war on U.S. military readiness.
