A US military investigation into the bombing of a girls' elementary school in Iran is finished, but Trump and Defense Secretary Pete Hegseth are reportedly hiding the findings — bad news for accountability and a sign something went badly wrong.

• US Tomahawk missiles hit a school in Manab, Iran, killing about 175 people, including over 100 children, in the opening of the February war on Iran.
• It was a "double tap" — a second strike hit parents and rescue workers who rushed in after the first, which is a war crime.
• Early findings blame 7-year-old targeting data that wrongly marked the school as part of an Iranian military base.
• Hegseth gutted the Pentagon's civilian-protection rules and bragged about scrapping "stupid rules of engagement," so the disaster fits a pattern.
• Possible culprits range from bad Israeli intel to a defense contractor like Palantir or Lockheed botching the coordinates — any of which would embarrass Washington.

Outlook: The report is unlikely to be released without a whistleblower, so the truth about who caused the deaths may stay buried.
