If it is permissible for the US government to kill citizens who engage in propaganda for an enemy while abroad, why is "Hanoi" Jane Fonda still walking around?
I mean really, we couldn't have laid on an airstrike just for her?
It is a justifiably doomed society that does not recognize the presence of a flaming beer bottle full of gasoline in a dead mans hand as prima facie evidence of justifiable homicide on the part of the citizen who laid such a hoodlum low with a well placed shot.
