Mahatma Gandhi frequently emphasized the inseparable link between ethics and spirituality. He argued that true morality must be rooted in religious conviction, which he defined broadly as the pursuit of truth. Without this spiritual foundation, he believed moral behavior lacked the necessary depth and endurance to withstand the challenges of life, comparing such a fragile existence to a structure built on shifting sand.

The concept of trusteeship, where property is viewed as a resource held for the benefit of the community or God rather than for absolute personal gain, gained significant traction with the spread of Christian ethics. Early Christian teachings emphasized stewardship, suggesting that wealth is a gift from God intended to be used for the welfare of others, thereby introducing a moral obligation to manage property responsibly for the common good.

Morgenthau argues that political realism is based on the concept of interest defined in terms of power. The autonomy of the political sphere implies that politics is an independent realm governed by its own laws, distinct from ethics, economics, or religion.

In August 1945, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki. These events occurred in the final stages of World War II and are widely considered to have accelerated the Japanese surrender. The use of these weapons remains a significant and debated topic in international relations, ethics, and the history of modern warfare.

Critics of the atomic bombings of Hiroshima and Nagasaki argue that Japan was already militarily defeated and on the verge of surrender due to the naval blockade and the Soviet entry into the Pacific War. They contend that the use of nuclear weapons was a geopolitical maneuver to intimidate the Soviet Union rather than a military necessity to end the war, sparking a long-standing historical debate regarding the ethics and strategic motivations behind the decision.
