The fight on the American right over Israel is now an open war between its biggest media voices, and it is bad news for anyone hoping the coalition holds together.

• Ben Shapiro said on Christian Broadcasting Network that Tucker Carlson "traffics in anti-Semitism" almost daily, arguing that Carlson's criticism of Israel and Zionists is really about Jews.
• Comedian Dave Smith, who is Jewish and libertarian, hit back that the argument is the same guilt-by-association tactic the right spent years condemning when the left used it.
• Smith's point: swap one word for another and you can make anyone sound like a bigot, so the test proves nothing.
• The deeper charge is that Shapiro's other stated principles bend whenever Israel is the issue, a claim that goes back to his old attacks on Ron Paul.
• The split is less about words than about policy — US support for Israel — and both sides are arguing past that.

Outlook: Expect the accusations to escalate as the right's pro-Israel and anti-war wings keep fighting for the same audience.
