They are responding to John Brennan's comment that "Jihad" is a legitimate tenet of Islam, Krauthammer again nails it...
Krauthammer: "Who is describing whom in religious terms? He's describing himself...Our enemy is describing itself in those terms and to deny it, is unbelievable"
Williams: "We don't want to antagonize people that we want to win over and that includes whatever moderate element there is in the Islamic community, we want them in fact to stand taller than they have been in defiance to people who are extremists. So I understand the instinct that says look, these people are Muslim radicals, why don't we just call it for what it is, well if you are politically savvy, you want to make sure that people who are faithful Muslims don't think we are going after them"
