NPR is not known as the most conservative radio station in the US. That's why I wanted to reference this program titled "Cautious Optimism on Behalf of the Iraq Surge". You can listen to it here.
I heard other references to writer Kenneth Pollack's op-ed in The New York Times, titled "A War We Might Just Win." (bytheyway, he had trouble with the word "win"). Pollack spoke out against the war early on, but in his editorial, he argues that U.S. troops are finally making progress in Iraq.
If you don't want to listen online, you can read some of his comments in an article titled "Pollack: ‘Surge’ Producing Real Progress in Iraq" at this webite.
