The Washington Post presents two differing opinions from two of its regular columnists.
Krauthammer: There are demonstrable successes on the ground, America must continue making the effort because of the size of the potential prize.
Kinsley: Sure, there are successes, but things aren't going the way they promised, they're not bringing the troops home yet, so it's time to bring them home.
Me, back when the invasion began in 2003, I wrote that it wold take 10 years to know if the gamble was successful or not. Sometime in the coming few weeks I intend to write a half-time report.
