Its unique role is to avoid national conflicts that can lead to violence and war as such occurrences are only looked at from an economic or political perspective rather than from a social and human perspective. People should be kept far and safe from violence.

What do we need to do when other member states are attacked? Collective defense is referred to be an official arrangement amongst nation-states to provide defense support to other states. It is differentiated not just by the geographical limitation, yet also through its foc us on the military obligations. Collective security denotes a variety of arrangements. While strictly speaking, the collective defense involves mutual commitments of other member states in the form of collective security, although geographically limited to military defense. However, collective security is regarded as the regional and international concept being represented by international institutions such as the United Nations and the League of Nations.

To summarize, national security is not something that may harm the well being of the nation or the people but instead, it involves their security and their freedom as well. The perception of social injustice as a nation�s security problems has become common but it is important to that social injustice or equality is domestic concerns and not an issue for national security. The collective aim of national security is to protect our nation as a whole at the basic level and to protect its people from external threats or attacks is its highest business.

Environmental security is a concept with a number of meanings. One among them is the more traditional idea of reacting to conflicts being caused by some environmental problems including energy disruptions, water shortages, and severe climate changes. As these problems are quite transnational, they may cause conflicts between nation-states. Another recent concept is to protect the climate and the environment.

It will be appropriate to end by justifying that security is not just a thing which is solely based on citizens well-being instead it�s an collaboration of various other aspects like security, safety and also regarding their freedom. Also, it is not inevitable to claim that social injustice was once a individualistic issue but now is the threat to the whole nation and is appropriately country�s security issue. The ideology behind social inequality and injustice is not restricted towards a domestic region but is applicable to every individual presenting the nation. So whilst compiling all concepts, national security is now been termed as not only with regards to securing national boundaries but also each individual residing in it by securing them from any sort of blitz or assail either externally or within.
