Here's a question: if it turns out the culprits behind the Karbala raid were not Iranian-trained but US-trained, should we attack ourselves? This just out from Fox of all places: "Several Iraqis have been detained for questioning in the ongoing investigation of at least two senior Iraqi generals suspected of involvement in an insurgent attack that killed five American soldiers on Jan. 20, U.S. officials told FOX News on Thursday."

(ed.note: In the original version of this post I incorrectly referred to Najaf rather than Karbala. It's hard for me to keep all the shady surge-era incidents straight sometimes. My bad.)
