If “Bush failed on 9/11” (an attack that was years in the planning & set up) after just 9 months in office and having kept most of Clinton’s top intelligence picks in place, then Clinton failed even worse after eight years in office, numerous Al Queda attacks on U.S. interests and leaving an intelligence community that had no more than “warnings” and little to no actionable intelligence about what was “warned”.
A mere “warning” is not in and of itself actionable intelligence that identifies who, when, where and how. At most it provides a tracer to the party that left the warning, but little more.
Clinton loaded the bases, Bush let them score.
