[From Richard Cohen of the *Wash­ing­ton Post*](http://www.washingtonpost.com/wp-dyn/content/article/2007/09/17/AR2007091701394.html):

The swipe at Petraeus was con­tained in a full-page ad the anti­war group MoveOn​.org placed in the New York Times last week. It charged that Petraeus was “cook­ing the books” about con­di­tions in Iraq and cited state­ments of his that have turned out to be either (1) not true, (2) no longer true, (3) pos­si­bly not true or (4) like every­thing else in Iraq, impos­si­ble to tell. **What­ever the case, using “betray” — a word asso­ci­ated with trea­son — recalls the ugly McCarthy era, when for too many Repub­li­cans dis­sent cor­re­sponded with disloyalty.**
