A split inside American Christian conservatism is getting louder, and it is bad news for leaders trying to keep the Israel question off the stage.

• Tucker Carlson was escorted off stage at a pro-life event after answering a question about Israel.
• His charge: Israeli military action has killed Christians and damaged ancient churches in Lebanon, Syria, the West Bank, and Gaza.
• The sharper attack was aimed at US Christian leaders who brush off Arab Christians there as Islamists.
• The underlying claim is that American political loyalty to Israel is now outranking concern for fellow Christians.

Outlook: Expect this fight over Israel to keep spreading through conservative and evangelical circles, with more public blowups like this one.
