During 21st Century, the term “National Security” has been redefined to include the non-traditional security challenges in addition to external military threats. The security and stability of any nation-state is dependent on a host of internal and external factors, such as economy, industrialization, literacy, size and quality of population, available national resources and military capability. Poor economic conditions lead to dissatisfaction which can then be exploited to create is harmony among the populace. Lower levels of literacy, when combined with poor economic conditions, can become a hot bed for terrorism. Weak national institutions lead to poor policy formulation and loss of trust in the government. External environments such as geographic location, unresolved disputes with neighbouring countries, regional alliances and big power interests also play an import role on a country’s security and stability.
