The creation of the Department of Homeland Security (DHS) is the most significant transformation of the U.S. government since 1947, when Harry S. Truman merged the various branches of the U.S. Armed Forces into the Department of Defense to be more capable of protecting the nation's defense against military threats.
DHS represents a similar consolidation of substance. After the terrorist attacks against America on September 11, 2001, President George W. Bush decided 22 previously separate agencies needed to be coordinated into one department to better be able to protect the nation against threats to the homeland.
Some of the various Department Components are as follows: BORDER & TRANSPORTATION SECURITY, EMERGENCY PREPAREDNESS & RESPONSE, INFORMATION ANALYSIS & INFRASTRUCTURE PROTECTION, SCIENCE & TECHNOLOGY, MANAGEMENT, COAST GUARD, SECRET SERVICE, CITIZENSHIP & IMMIGRATION SERVICES, STATE & LOCAL GOVERNMENT COORDINATION, PRIVATE SECTOR LIAISON.
In addition to the large number of employees in these departments in the past, even more are necessary now because America must constantly be prepared and vigilant. Computer workers must be able to analyze and provide instant information concerning our country as well as to supply information from anywhere in the world. Therefore, there are thousands of positions not only for those qualified to "carry guns," but also in order to fill the many kinds of necessary positions which must be in place to "back-up" our law enforcement agents.
