The key to terror, the key to terrorism, is not the act - but the fear of the act. That is why bin Laden and his deputies and his imitators are forever putting together videotaped statements and releasing virtual infomercials with dire threats and heart-stopping warnings. But why is the Republican Party imitating them? Bin Laden puts out what amounts to a commercial of fear; The Republicans put out what is unmistakable as a commercial of fear. The Republicans are paying to have the messages of bin Laden and the others broadcast into your home.
