There are degrees of dereliction and I'll guarantee you that if President Bush had not pursued the path that he chose (along with the majority in Congress) he too would have been accused of being a coward, a sellout and everything else under the sun. I remember quite well that the loudest voices for going after Saddam Hussein were from Dumycrats; like Senator Rockefeller, Kennedy, the Clintons and others.
As a matter of fact, President Bush might be accused of persuing our enemies, but hardly the opposite as is the case in regard to Benghazi. You just have to understand the difference between apples and oranges.
