Which of the following concepts is not typically considered a pillar of military strategy for the United States?

Economic support is not typically considered a pillar of military strategy for the United States, as military strategy primarily focuses on concepts that directly relate to achieving and maintaining military effectiveness and readiness. The other concepts listed are fundamental to military strategy.

Deterrence involves preventing adversaries from taking aggressive actions through the threat of military retaliation or the promise of military response. It is a key principle that seeks to maintain stability by making the costs of aggression outweigh any potential benefits for an adversary.

Alliance solidarity is crucial in military strategy as it emphasizes partnerships and collaborative defense efforts with allied nations. The strength of military alliances can enhance collective security, enable shared resources, and foster a unified response to threats.

Forward defense refers to the strategy of positioning military forces in advance of potential conflict areas. This approach aims to deter aggression by demonstrating military readiness and capability in close proximity to potential threats, thereby shifting the battlefield away from the homeland.

While economic support can indeed play a role in national security and the broader strategy of a country, it is primarily categorized under diplomatic and economic policy rather than military strategy itself.
