As violence intensified in the Middle East last week, it also sparked a fiery debate on the presidential campaign trail over foreign policy. The issue has taken a back seat to jobs and the economy in 2012, but the turmoil across the Arab world forced the issue front and center for the first time in the race. For President Barack Obama, the violence is a test of his handling of the Arab Spring uprisings and his promises of democracy there. And for Republican challenger Mitt Romney, questions remain over what principles would guide his decisions on the world stage. Guest host Susan Page of USA Today discusses presidential politics and foreign policy with her guests.
