The Department of Homeland Security was established in the year 2002 as a part of the United States effort to combat against terrorists attacks. It was also instituted to respond against natural disasters that will greatly affect the United States people. Its primary goal is to protect the civilian inside or out of the country. Its main functionality is to prepare for actions to respond to domestic crisis. It also provides regulation on cyber security issues. The said department set color codes to describe the threat levels of terrorists in the country. Being well regarded as one of the largest department in the federal cabinet, this department should think of ways on how to perform its function to protect the people of the United States of America.
From the said functions of the department of homeland security, it is the role of the concerned department to deal with problems arising that would threaten its citizen. It should not interfere with the scope of work of the other departments. There are a lot of work to be done in monitoring possible threats by the terrorists against the lives and properties of the United States people. Likewise, the department also helps in dealing with people affected by various calamities such hurricanes, earthquake, flash floods and other nature-driven calamities.
With respect to the military’s role, the main difference is that the military is not being used to meddle with the domestic issues or internal affairs but for combat and monitoring of the country’s security. Normally, military is under the command of the Department of National Defense, the department focused on military affairs overseas. This can show the major role differences played by both the military and the homeland security department. In the same way, the military should be cautioned not to go beyond its jurisdiction particularly with the civilian communities. Their participation should be limited on providing assistance on calamity-affected populace together with the other agencies of the government.
