The most important guidance for military operations is a nation's grand strategy, and consequently any wartime strategy should work under the purview of grand strategy to achieve its political or diplomatic objectives. Being the two elements of military strategy, both offensive and defense strategies must also be subservient to grand strategy. Although it is easier to discuss offensive and defensive strategies separately, they are mutually dependent on each other and so intertwined that, in actuality, one is ultimately not successful without the other. As the conduct of warfare throughout history has shown, to successfully employ offensive attacks, the lines of resupply and the bases of operations must be protected through defensive means. As a result, any wartime strategic plan should include both offensive and defensive strategies. Some critics may counter with the adage, "the best defense is a good offense," or misapply Clausewitz that the "destruction of the enemy" is the key to victory, thus implying that offensive operations are the supreme consideration in war. 1 Granted that an offensive strategy during military operations is a necessary requisite to achieve final victory, defensive strategies in some locations allow for more effective and subsequently more successful offensive measures in other locations.
