The nature of war remains timelessly unchanged. However, its form is constantly evolving. We are now transitioning from conventional warfare to hybrid warfare, where there are no boundaries and restrictions.

Now there is a need for theoretical and practical understanding for deterrence (strategic dimension) and defense (operational/tactical). The lessons learned so far from the war in Ukraine are being analyzed thoroughly. The Greek choices between deterrence and defense after 1974 give the author an opportunity to propose a new military philosophy for the present and the next decade.
