Kevin Peraino on Lincoln's foreign policy

Q: I know this is almost an impossible task, but if you had to describe it, what’s the Lincoln Doctrine?

A: Lincoln said it himself: “One war at a time.” And I think that’s the bumper sticker for Lincoln. He just didn’t want to do anything during the Civil War that was going to make his job at home more difficult.

That’s how he led the country, and set the stage for American power in the decades since.
