E-mail (I edited out some abrasively harsh bits):

Dear Rich: … you might remind [Derb] that ARVN was more than holding its own when our troops left Vietnam in 1973. In fact, for all intents and purposes the Vietnam war had been won in 1973. It was not until 1975 when we made the sickening move to cutoff supplies to the South Vietnamese that ARVN fell apart….
Derb [says]… that we Americans should go after our enemies hammer and tong. And yet, when it comes to going after people in Iraq who have manifestly been killing our people, Derb suddenly gets the willies. Why is that? Could someone attempt to pin him down on his expressed position of going after American-killers unto the ends of the earth, except when they happen to be Al Qaeda and/or Baathist fascists who have been killing Americans in Iraq.
