Principles of Warfare of Sun Tzu Applied to WW2

Recommendation for Truman

Introduction

In the critical juncture of April 1945, President Truman sought strategies to end the war with Japan decisively within a year, explicitly excluding the use of nuclear weapons. This essay recommends an approach that incorporates the maritime strategy of Alfred Thayer Mahan and the principles of warfare articulated by Sun Tzu. This recommendation is based on an understanding of the importance of naval power, economic blockade, psychological warfare, and strategic diplomacy.

Mahanian Strategy: Command of the Sea

Alfred Thayer Mahan's work, The Influence of Sea Power upon History, 1660-1783, emphasizes the decisive role of naval dominance in achieving geopolitical objectives. Based on what Mahan would say for the Pacific theater, establishing uncontested control over sea lanes is important for several reasons. To this end, strategy should focus on blockades for the purpose of economic warfare, and amphibious operations.

First off, a stringent blockade would sever Japan's access to essential resources, notably oil, rubber, and metals, crippling its war machinery. Mahan's doctrine suggests that such a blockade could force Japan into a position of unsustainable scarcity, pressuring it towards capitulation.

Second, having control of the sea would enable the launch of amphibious assaults on strategic islands. This in turn would assist with further isolating Japan. It would also be a way of providing bases for air operations against the Japanese mainland.

The Mahanian strategy is thus both practical and feasible. It would assist in reducing Japan’s ability to continue to wage war. Thus, an end to the war could come into sight with this approach. However, if this approach is coupled with the principles of Sun Tzu, it cannot fail to achieve the objective.

Sun Tzu's Principles: Flexibility and Intelligence

Sun Tzu's The Art of War offers strategic principles that complement Mahan's focus on sea power. Among these are the importance of intelligence, psychological warfare, and strategic flexibility.

First of all, Sun Tzu posits that victory can be achieved by understanding the enemy’s intentions and capabilities. Implementing superior intelligence efforts would enable the U.S. to anticipate and counter Japanese moves, and thus reduce the conflict's duration and cost.

Secondly, an element of psychological warfare can be combined with economic warfare (blockades). Thus, Sun Tzu also emphasizes the role of psychological strategies in undermining the enemy’s will to fight. Propaganda campaigns highlighting the inevitability of Japan's defeat and encouraging defection could demoralize Japanese forces and erode public support for the war effort.

There is also an indirect approach that can have benefits according to Sun Tzu. Avoiding direct confrontation when the enemy is strong but striking where they are weak is actually core tenet of Sun Tzu's strategy. This suggests prioritizing targets in the Pacific that are strategically valuable yet less heavily defended, facilitating a gradual tightening of the noose around Japan's industrial and military capabilities.

Taken together, therefore, one can see that Sun Tzu’s principles help to support and broaden the strategic approach of Mahan with respect to bringing the war in the East to a close. Both approaches, moreover, are supported by the argument of Joseph Wylie. Joseph Wylie's insights in "Reflections on the War in the Pacific" highlight two strategic tactics: sequential and cumulative strategies. Sequential strategies involve discrete steps where each action leads naturally to the next, exemplifying planned campaigns across the Pacific. Cumulative strategies, on the other hand, consist of individual actions that accumulate impact over time, such as psychological or economic warfare, where no single action directly depends on another but collectively contributes to the outcome. Wylie suggests that even though the sequential strategy offers predictability, the cumulative strategy, which can be harder to forecast, can also bring an adversary to the brink of defeat through the attrition of resources, as seen in the tonnage war waged by American submarines against Japanese merchant shipping. His analysis is helpful in showing the importance of integrating both strategies for effective warfare, suggesting that the strategic success may hinge on balancing sequential and cumulative efforts to achieve goals with minimal costs.

In other words, the combination of Mahanian strategy with Sun Tzu’s principles is basically a reflection of what Wylie argues for in terms of having sequential and cumulative strategies in place. To defeat an opponent, one must think both sequentially and cumulatively. Mahanian strategy could be said to represent the sequential tactic; the application of Sun Tzu’s principles could be said to represent the cumulative tactic.

Counterargument: The Limits of Sea Power and Psychological Warfare

One could argue that relying solely on sea power, as Mahan suggests, may not fully account for the logistical complexities of sustaining a large-scale naval operation across the vast expanse of the Pacific. The extended supply lines and the need for secure bases could pose significant challenges. Furthermore, the reliance on psychological warfare and strategic flexibility might not be as effective against Japan's Bushido code, which instilled a culture of sacrifice and resilience among its soldiers and citizens, potentially diminishing the impact of such strategies. Thus, neither in isolation or in combination would either the Mahanian or Sun Tzu principles be effective.

Rebuttal

Although these critiques highlight real challenges, they do not diminish the validity of a combined Mahanian and Sun Tzu approach. Technological advancements and innovations, such as improvements in naval logistics, communications, and intelligence, can address the logistical hurdles, making sustained operations across the Pacific feasible. The island-hopping campaign demonstrated how forward bases could be secured and used effectively against Japan, minimizing the logistical strain.

Moreover, even the robust Bushido ethos has its limits. The cumulative effect of a comprehensive blockade, strategic bombings, and the psychological warfare aimed at undermining the morale of both military personnel and the civilian population can gradually erode the will to fight. The integration of these strategies, along with diplomatic efforts to isolate Japan internationally, can create a multifaceted pressure that challenges Japan's capacity to continue the war, despite its cultural predispositions.

The interplay of these strategies, grounded as they are in the principles of both Mahan and Sun Tzu, gives focus on the appropriate strategy for bringing the war against Japan to a speedy conclusion. The strategy must be one that combines the strength of the West to practically and feasibly undermine the strength, both moral and military, of Japan. Thus, this recommendation consists of a dual approach in terms of applying naval dominance while at the same time also exploiting the strategic weaknesses of the adversary. This strategy is appropriate as it addresses the direct military confrontation and also targets the broader socio-economic and psychological aspects of warfare, creating a comprehensive pressure mechanism aimed at hastening the end of hostilities without resorting to nuclear options.

Incorporating Clausewitz’s Concept of the Culminating Point

Carl von Clausewitz’s notion of the "culminating point of victory" further refines this strategy, suggesting a point in the campaign after which the continuation of offensive operations becomes counterproductive. Recognizing this point would prevent overextension and conserve resources for the post-war reconstruction phase. Alongside Wylie’s emphasis on the significance of cumulative strategy alongside sequential strategy, this approach supports a blend of direct military actions with sustained efforts like economic warfare and psychological operations to weaken Japan's resolve and capacity to continue the war effort. Clausewitz’s idea reinforces the necessity of aligning military strategies with political objectives, emphasizing the role of war as an instrument of policy rather than an end in itself. Clausewitz's notion of the "remarkable trinity" - the interplay between the people, the army, and the government - highlights the complexity of warfare and the need for strategies that consider the moral and political dimensions of the conflict.
