On Monday, the Pentagon's Inspector General released a special report on the Iran war. The report covers the start of the conflict on February 28 through June 30\. Its conclusions are not surprising. They are official. [The Inspector General acknowledged the depletion of key US munition stockpiles](https://www.nbcnews.com/politics/national-security/pentagon-watchdog-says-iran-war-led-munitions-shortfall-rcna597019?ref=diplopolis.com) and documented damage done to hundreds of structures at American military bases in the Middle East. The report says what DiploPolis reported first in August and what Hegseth denied at a Senate hearing in July: the stockpiles are depleted, the bases are damaged, and the official public account of both was not accurate.

DiploPolis published 'Dangerously Low' on August 5, reporting that the US had burned through nearly 80 per cent of its THAAD missile interceptor inventory and more than half of its Patriot stocks. Hegseth told Congress in July that the inventories were in 'very good shape.' A senior general told the same Congress that without additional funding, the Pentagon would not get the munitions it needs. The Inspector General's report is the official accounting of the gap between those two statements. Hundreds of structures at US bases in the Middle East were damaged by Iranian strikes. [The stockpiles of four key munitions systems were at or below 50 per cent of pre-war levels.](https://www.cnn.com/2026/09/14/politics/iran-war-pentagon-watchdog-report?ref=diplopolis.com) These are the IG's conclusions, not external analysis. The government's own internal watchdog has confirmed what the government's external spokespeople denied.

[The IG report also confirmed the war had cost an estimated $33.4 billion through June 30,](https://www.globalsecurity.org/military/library/news/2026/09/mil-260915-rferl03.htm?ref=diplopolis.com) of which $22.3 billion was spent on expended munitions alone. The report covers only through June 30\. The war resumed in July. The five tankers destroyed in September, the 18 missiles launched at Jordan, the destruction of the Kaviz and Charminar and Horizon 1 and the Riesco and the Derya — all of that is not in the report because it happened after June 30\. The interceptors depleted since July are not in the report. The report that covers February 28 to June 30 is already history. The war has continued for 78 days since June 30.

The significance of the IG report is not its findings. Those were already known by people paying attention. Its significance is its category: official. The Inspector General is not a journalist or an analyst or a senator asking pointed questions. It is the executive branch examining itself and producing a document that says, in the formal language of government oversight, that the stockpiles are depleted and the bases are damaged. [When the government's own watchdog says what outside observers have been saying for months,](https://www.washingtonpost.com/politics/2026/09/15/iran-war-has-caused-strategic-munitions-shortfall-inspector-general-report-says/?ref=diplopolis.com) the dispute about what is true becomes harder to sustain. The report will not be cited by the administration. It is the record.

Saudi Arabia, facing the same stockpile problem from the other side of the Strait, has now turned to France, the United Kingdom, Pakistan and Egypt for air-defence support, according to two regional officials. The US interceptors that were supposed to protect the Gulf are depleted. The Gulf is now asking the same allies the US called shameful for not joining the war to help provide the air defence the war has consumed. The IG confirmed what DiploPolis reported. The cascade continues.
