A public fight has broken out on the American right over support for Israel, pitting figures against each other and turning nasty.

• Ben Shapiro and JD Vance are trading shots over how strongly the U.S. should back Israel.
• The clash exposes a growing split among conservatives who once stood together on the issue.
• Critics accuse pro-Israel voices in media and Congress of pushing the country into Israel's wars.
• The tone turned ugly, with harsh personal attacks and claims that support is bought and paid for.

Outlook: The rift over Israel is likely to keep deepening and dividing the right heading into the election season.
