COMMENTARY
Cold war liberalism had a fine run in the middle third of the 20th century, and it has lingered here and there since. Scoop Jackson kept the flame alive in the 1970s. Peter Beinart wrote a book called “The Good Fight,” giving the tendency modern content.
But after Vietnam, most liberals moved on. It became unfashionable to talk about evil. Some liberals came to believe in the inherent goodness of man and the limitless possibilities of negotiation. Some blamed conflicts on weapons systems and pursued arms control. Some based their foreign-policy thinking on being against whatever George W. Bush was for. If Bush was an idealistic nation-builder, they became Nixonian realists.
Barack Obama never bought into these shifts. In the past few weeks, he has revived the Christian realism that undergirded cold war liberal thinking and tried to apply it to a different world.
