DHS represents a similar consolidation, both in style and substance. In the aftermath of the terrorist attacks against America on September 11th, 2001, President George W. Bush decided 22 previously disparate domestic agencies needed to be coordinated into one department to protect the nation against threats to the homeland.
The new department's first priority is to protect the nation against further terrorist attacks. Component agencies will analyze threats and intelligence, guard our borders and airports, protect our critical infrastructure, and coordinate the response of our nation for future emergencies.
Besides providing a better-coordinated defense of the homeland, DHS is also dedicated to protecting the rights of American citizens and enhancing public services, such as natural disaster assistance and citizenship services, by dedicating offices to these important missions.
