LIKE HERPES SIMPLEX, Jesse Jackson never really goes away—he just lies dormant. Clearly, the present national crisis was too much for him to resist. So Jackson last week announced he had received an "invitation" from the Taliban to lead a "peace delegation" to Afghanistan. Of course, Jackson, judicious fellow that he is, subsequently said that he "must weigh what this invitation means." Additionally, he asserted that he "was surprised that I heard from them." Not as surprised as the Taliban, it turns out, who claim they extended no such invitation—it was Jackson who invited himself.
