The department of homeland security is one of the most powerful institutions in the United States that exhibits a centralized structure. The creation of the department of homeland security merged many Federal agencies thus bring many employees together (Pittman, 2009). With the central role, of securing the United States from threats, the department of homeland was created as an answer to the vulnerability of the United States against terrorist attacks as she was hit in 9/11. The establishment of the department of homeland security was created through the amalgamation of, Federal Emergency Management Agency, the immigration and naturalization service, the U. S Coast Guard, and U.S custom service were all brought under one roof making (Pittman, 2009).
The need to have proper coordination against terrorism attacks underscored the formation of the department of homeland security. Through bringing a number of federal agencies, the department of homeland security strives, to coordinate these agencies that we once on their own. The department of homeland security is at the heart of the organization and tops in the hierarchy and is responsible for directing all operations. The centrality of the department of homeland gives it a mandate over the smaller agencies who execute roles that meet the goals of the department (Mockaitis, 2008). At the top of the hierarchy, is the department of homeland security that draft policies that affect the individual agencies.
Each of the agencies under the department of homeland security has a given role and association with the department. The Federal Emergency Management Agency operates under the department of homeland security and oversees disaster whether human, climatic or technological. With the absorption of FEMA into the department of homeland security, this agency has been tasked with managing disaster as well as coordinating recovery methods. Despite the diplomatic clout surrounding the department of homeland security, FEMA is charged with funding emergency programs through grants under supervision.
The U. S Coast Guard is another agency that now falls under the department of homeland security. The department of homeland security is also concerned with securing the United States waters and this involves the U.S Coast Guard (Nicholson, 2005). This agency under the department of homelands security is charged with preventing terrorism in the territorial waters of United States. The role of U.S Coast Guard underlies the challenge of preventing maritime terrorists that target the United States. With the interaction of the department of homeland security and the U.S Coast Guard, the United States maritime environment is secured from terrorist.
The immigration and naturalization service is also under the department of homeland security. The United States can be vulnerable if terrorist are allowed into its borders. Because of such a danger, the department of homeland security and immigration and naturalization work to prevent entry of terrorists into the United States. The immigration and naturalization service allows legal movement of people into and out of the United States borders, as well as enforcing migration laws. The immigration and naturalization service works to grant immigration rights the benefit of residing in the United States and thereby blocking terrorists (Bullock et al., 2008).
The U.S custom service is also an agency under the department of homeland security. This agency works under the department of homeland under customs given imports into the United States can be used to import weapons. This agency falls under the control of the department of homeland security with its activities being controlled by the department. The specific roles of the U.S custom service include enforcement of U.S regulations that limit the entry of weapons or other illegal contraband that may be used by terrorism to hurt American interest. Indeed, the centralization of the department of homeland security has brought several agencies into a single centralized organization.
