Rebuild the Twin Towers exactly as they were except have a memorial area on each floor dedicated to the memories of those who worked there.
firemen and police officers who gave their lives would be memorialized in the lobby of each building.
Included in the lobby would also be a listing of all the names of all 9-11 victims and the floor where their memorial can be found.
Bring the towers back, as they were, best embodies the resolve of the
United States and the memorials within them will allow the memories to endure!
