More and more, I think E.J. Dionne's interpretation is correct.
Bill Clinton's eruption on "Fox News Sunday" last weekend over questions about his administration's handling of terrorism was a long time coming and has political implications that go beyond this fall's elections.
By choosing to intervene in the terror debate in a way that no one could miss, Clinton forced an argument about the past that had up to now been largely a one-sided propaganda war waged by the right. The conservative movement understands the political value of controlling the interpretation of history. Now its control is finally being contested.
