Anti-Israel posturing is for many people the cheapest route to the appearance of virtue. So it is with British Deputy Prime Minister Nick Clegg and the Tory peer Baroness Sayeeda Warsi. Both have in recent days called for the suspension of U.K. arms-export licenses to the Jewish state. The Baroness took the further step on Tuesday of resigning her post as a Foreign Office Minister over David Cameron's "morally indefensible policy" on Gaza, as she put it in a letter to the Prime Minister.

The usual media suspects frame this minor rebellion as a heavy blow against Mr. Cameron: As the Liberal Democrat leader, Mr. Clegg is the junior partner in the coalition government; Baroness Warsi, meanwhile, is said to represent a groundswell of Tory discontent over Britain's mildly pro-Israel policy.

All that may be, but Mr. Clegg's and the Baroness's gesture politics also expose their own inconsistent moral outrage.
