The New York Times offers a long take on John McCain's foreign policy views, and a brief column on some of Barack Obama's. In a Sunday magazine piece, writer Matt Bai examines McCain's stance, shaped in part by Vietnam, in a lengthy article.

(S)ome suspect that whatever lesson McCain took away from his time in Vietnam, it was not the one that stayed with his colleagues who were "in country" during those years - that some wars simply can't be won on the battlefield, no matter how long you fight them, no matter how many soldiers you send there to die.

And for a brief column, David Brooks talks to Obama to explore his perspectives on foreign intervention.

"I constantly reject this notion that any hint of strategies involving diplomacy are somehow soft or indicate surrender or means that you are not going to crack down on terrorism. Those are the terms of debate that have led to blunder after blunder."
