What is the "Bush Doctrine"?

Sarah Palin doesn't seem to know. Moose in the headlights moment?



UPDATE: The McCain camp i'm sure has prepped her on the current events issues like Iran, Iraq, Pakistan, Georgia, North Korea and even the difference between Sunni and Shiite.

But they have overlooked the simplest things like the "bush doctrine", whose last big mention was in 2006, when the pundits have declared it dead.

UPDATE: there are two ways to interpret the "bush doctrine"

1) use military force to spread democracy (freedom is on the march)
2) or, pre-emptive strike against an enemy.
