DAVID WEIGEL: Obama’s Wars: Liberal Interventionism Makes a Comeback. “Obama believes all of what he said six years ago in Chicago. He has called for, or retroactively endorsed, interventions in Zimbabwe, Pakistan, and Sudan. He has advocated a humanitarian-based foreign policy for his entire public career. Since coming to the U.S. Senate in 2005, he has built up a brain trust of academics and ex-Clintonites who, like him, challenge the logic of the Iraq war but not the logic of wars like Iraq. John McCain looks at American military power and sees a way to ‘roll back’ rogue states. Obama looks at American military power and sees a way to solve international and intranational conflict, regardless of the conflict’s immediate impact on national security. McCain seeks to aggressively confront imminent threats. Obama wants to do the same, while forestalling threats of tomorrow with just as much military vigor.” Hmm.
