B. No one seriously imagines that peace can come to the Middle East without America.
C. Yet a president who understands, as Mr. Bush did not, that America is not the uncontested hyper power of the 1990s-one who values “soft power” more than the hard version-will be a change for the better.
D. An America led by such a man will listen more carefully to and work more closely with allies and rivals, will strive harder to respect the laws it has signed up to and might enter into new commitments, for instance to tackle climate change.
