Your argument is so stupid you are losing a lot of credibility. So Clinton's aids advised it and he did not implement it and neither did Bush so it is Bush's fault?
However, this is not the case. Plans for the Department of Homeland Security and the Homeland Security Act were underway as early as 1998. In 1998 the United States Commission on National Security/21st Century began working on a report called Road Map for National Security: Imperative for Change, which was issued January 31st 2001. This report called for the creation of a National Homeland Security Agency.
The Commission was actually put together by the Clinton administration and supported by Senator Lieberman. The Bush administration was initially against the idea of the Department of Homeland Security because it was part of the Clinton legacy. However, the initial report by the Commission has been significantly changed and added to by the Bush administration since 9/11.
