Fouad Ajami wrote an interesting editorial in the Wall Street Journal where he compares the foreign policy approaches of Obama and McCain
So the Obama candidacy must be judged on its own merits, and it can be reckoned as the sharpest break yet with the national consensus over American foreign policy after World War II… In their view, we can make our way in the world without the encumbrance of “hard” power. We would offer other nations apologies for the way we carried ourselves in the aftermath of 9/11…
When we elect a president, we elect a commander in chief. This remains an imperial republic with military obligations and a military calling… The warrior’s garb sits uneasily on Barack Obama’s shoulders: Mr. Obama seeks to reassure Americans that he and his supporters are heirs of Roosevelt and Kennedy; that he, too, could order soldiers to war, stand up to autocracies and rogue regimes. But the widespread skepticism about his ability to do so is warranted.
