I awoke this morning to the horrifying news of the death of U.S. Ambassador Chris Stevens and three other consular officials during a mob attack on the consulate in Benghazi, which followed yesterday's storming of the Embassy in Cairo. The embassy riots over an absurd, obscure anti-Islam movie are more "Danish Cartoons" than "Iranian Hostage Crisis" and were following a depressingly familiar script until the deaths in Libya. But now the stakes are far higher. It would be a tragic mistake to allow the images from Cairo and Benghazi to undermine American support for the changes in the Arab world. The protestors in Cairo and Benghazi are no more the true face of the Arab uprisings than al-Qaeda was the face of Islam after 9/11. We should not allow the actions of a radical fringe to define our views of an entire group. The aspirations for democratic change of many millions of Arab citizens must not be delegitimated by the violent acts of a small group of radicals.
