Saturday night's Democratic debate was supposed to center on domestic policy, but after the attacks in Paris, it was altered to focus in large part on terrorism and foreign policy. On one hand, that was necessary - when sudden and important events happen in the world, the people who want to lead our country have the chance to show why they ought to be in charge and give some sense of how they'd handle crises. On the other hand, without a lot of time for reflection, chances were high that the discussion would produce more heat than light.
And so it was that a significant portion of the debate's terrorism section centered on the question of whether the candidates, particularly Hillary Clinton, have used the appropriately belligerent terminology in discussing terrorism. Bernie Sanders and Martin O'Malley got involved, but the critical exchange was between moderator John Dickerson and Clinton:
DICKERSON: "Secretary Clinton, you mentioned radical jihadists. Marco Rubio, also running for president, said that this attack showed and the attack in Paris showed that we are at war with radical Islam. Do you agree with that characterization, radical Islam?"
