Obama's challenge

Andrew Bacevich:

The challenge facing Obama is clear: he must go beyond merely pointing out the folly of the Iraq war; he must demonstrate that Iraq represents the truest manifestation of an approach to national security that is fundamentally flawed, thereby helping Americans discern the correct lessons of that misbegotten conflict.

By showing that Bush has put the country on a path pointing to permanent war, ever increasing debt and dependency, and further abuses of executive authority, Obama can transform the election into a referendum on the current administration's entire national security legacy. By articulating a set of principles that will safeguard the country's vital interests, both today and in the long run, at a price we can afford while preserving rather than distorting the Constitution, Obama can persuade Americans to repudiate the Bush legacy and to choose another course.

This is a stiff test, not the work of a speech or two, but of an entire campaign. Whether or not Obama passes the test will determine his fitness for the presidency.
