Mitt Romney is on tour. This morning he arrives in London, where he’ll watch the Olympic opening ceremony on Friday before moving on to Poland and Israel.
Romney’s international travels have drawn attention to his foreign policy, or rather, what's unknown about his foreign policy. So far, he has been quick to criticize Obama's handling of Iran. But now he's coming under pressure to define his own doctrine. What do these travels say about what a Romney doctrine could look like?
Speaking to this is David Sanger, chief Washington correspondent for The New York Times.
