This strategy marked a shift from previous military doctrines by focusing on cost-effective military preparedness and relying on nuclear capabilities to ensure national security without maintaining large conventional forces, which was especially relevant during the tensions of the Korean War and the broader context of the Cold War.
Arms race: An arms race is a competition between two or more nations to achieve superior military capabilities, often through the accumulation of weapons and military technology. This phenomenon typically emerges during times of geopolitical tension, where countries feel the need to enhance their military strength to deter adversaries or assert dominance. The arms race played a crucial role in shaping international relations during the Cold War, leading to significant military expenditures and advancements in weaponry, particularly nuclear arms.

China: China refers to a nation in East Asia, known for its ancient civilization and significant global influence. During the Korean War and the Eisenhower Era, China emerged as a major communist power under Mao Zedong, affecting the geopolitical landscape of the time.

Cia-backed coup: A CIA-backed coup refers to a covert operation orchestrated by the Central Intelligence Agency to overthrow a foreign government, often to promote U.S. interests.

Communism: Communism is a political and economic ideology that aims for a classless society where all property is publicly owned, and each person works and is paid according to their abilities and needs. This ideology became a significant factor during the 20th century, particularly in the context of global tensions, as countries aligned themselves either with or against communism, leading to significant geopolitical conflicts and struggles for influence.
Containment: Containment was a foreign policy strategy aimed at preventing the spread of communism during the Cold War. This approach was rooted in the belief that if communism could be contained within its existing borders, it would eventually collapse under its own weight. The strategy shaped U.S. diplomatic and military actions as it sought to curb Soviet influence globally, impacting various geopolitical conflicts and alliances.
Democracy: Democracy is a system of government in which power is vested in the people, who exercise that power directly or through elected representatives.

Proxy war: A proxy war is a conflict where two opposing countries or groups support combatants that serve their interests instead of directly fighting each other.

This strategic approach allowed them to exert power and compete on a global scale while minimizing the risk of nuclear conflict.
