A push to impeach Defense Secretary Pete Hegseth has opened a fight inside the right over a strike that killed children, and it is bad news for the administration's war footing.

• Rep. Thomas Massie has filed impeachment articles against Hegseth.
• The core demand is an apology from Trump and Hegseth for a strike that killed young girls.
• Anyone in charge who refuses to apologize should be removed from office.
• Talk of using nuclear weapons offensively, and the use of AI to pick targets, are treated as firing offenses and possible crimes.
• The argument is that the U.S. has to hold itself to a higher standard than Iran to keep public support.

Outlook: The impeachment push is unlikely to pass, but it deepens the split among conservatives over the Iran conflict and how it is being fought.
