Each independent State faces challenges to its core interests, among them survival as a geopolitical entity with all its territory intact.
The challenges come in different ways, ranging from insults to its honour and citizens questioning its legitimacy as a state, misuse of international organs, disparaging its values and belief systems, or direct aggression through the land, sea or air. To safeguard those interests from internal and external threats, states create and build assorted security or defence mechanisms.
