A group of anti-war conservatives is breaking with Trump to build a new party, which is bad for Republican unity and good for those who want fewer foreign wars.

• Marjorie Taylor Greene, Tucker Carlson, Tom Massie, and Joe Kent met and declared a new "America First" movement, saying Trump betrayed his promise to avoid foreign wars.
• The split started over the Epstein files and grew as Trump backed Israel and attacked the group as traitors.
• The fight is really MAGA versus MAGA — one side wants no more wars, the other, led by Laura Loomer and Mark Levin, stays loyal to Trump and Israel.
• A new party could only win if both Democrats and Republicans keep nominating pro-Israel candidates, leaving those voters nowhere else to go.
• Even without winning, the movement pressures the GOP much like the left pushes Democrats, especially with young voters who care about ideas over party.

Outlook: The real battle over the party's direction is aimed at 2028, once Trump is off the scene.
