Final answer:
Intergovernmental Organizations (IGOs) like NATO require a broad range of military capabilities including air superiority, naval power, and cyber warfare to deter threats and maintain security, therefore, the correct answer is 'All of the above'.
Step-by-step explanation:
In most situations, Intergovernmental Organizations (IGOs) need a comprehensive military capability that includes air superiority, naval power, and cyber warfare capabilities. The concept of hybrid warfare, which has emerged in the 21st century, depicts modern military engagement as a blend of multiple fronts including political, conventional, irregular, and cyber warfare.
Organizations such as NATO require strong military capabilities to deter aggression and respond effectively to threats in today's dynamic global landscape. Accordingly, they must maintain a broad spectrum of military competencies to ensure the security of their member states and to uphold international peace and stability.
Therefore, the correct answer is 4) All of the above.
