Tucker Carlson turns hard against Trump, a sign of a widening split on the pro-Trump right over foreign policy and personal loyalty.

• Trump reportedly mocked Joe Kent, saying he "got remarried awful quick" after his first wife was killed in Syria.
• Kent's wife, a service member, died during the U.S. mission in Syria — a war Kent later argued America should have left.
• The attack ties into a bigger fight on the right over pulling troops out of the Middle East and how much U.S. policy bends to Israel.
• Kent is cast as loyal and mistreated, while Trump is blasted as petty and wrong on the merits.

Outlook: Expect more open feuding between Trump and once-friendly nationalist voices as the anti-war wing pushes back harder.
