A heated argument over whether Trump is treating Israel too harshly, framed as a sign of growing splits on the right over US backing for Israel.

• Trump has called Iran's leaders reasonable while saying Netanyahu is a difficult guy to deal with.
• The pushback: Trump is being disrespectful to Israel by treating it as a junior partner instead of an equal ally.
• The counter-argument: Israel acts in its own interest, not America's, and used the war as cover to grab land in Lebanon.
• The bigger fight is over whether the US owes Israel anything after spending American money and lives on the conflict.

Outlook: Expect the split among conservatives over how much to support Israel to keep widening.
