Detonation of the atomic bomb in Japan is a debate that still holds controversies and criticism. It is evident that the prominence of domino theory in the 1950s and late 1980s significantly influenced the decision (Olson & Roberts, 2011). Domino theory highlighted that a state with the influence of communism could quickly make surrounding countries follow the practices in a domino effect. Therefore, the American administrators used the idea to justify their decisions during the cold war. It also explains the Americans decision to bomb Japanese cities of Nagasaki and Hiroshima towards the end of World War II.

The atomic bomb brought to a halt the World War II. America made the decision to attack Japan in the most devastating manner after the nation refused an unconditional surrender. The widespread effects that had long lasting effects triggered divergent views. A section of the world supported the decision while others condemned United States actions (Olson & Roberts, 2011).

Nations that support the decision and domino theory point to the unprecedented expansion of communist rule in the Southeast Asia. Notably, the formation of the Democratic Republic of Vietnam raised concerns about controlling the spread of communism. Therefore, the cold war and the preceding politics served to save the whole world (Lisiero, 2008).

Second, domino influence helped the especially in Indochina helped ASEAN nations to plan for economic growth by preventing domino influence. Therefore, American interventions never weakened the Soviet Union or ended Cold War. Besides, the domino influence promoted economic prosperity in the poorer nations and strengthened their armies (Olson & Roberts, 2011).

On the other hand, arguments against the domino theory entailed fears of accumulation of atomic and nuclear weapons by other countries. Thus, the American decision against Japan was justified. However, the historical developments around the issues have facilitated warfare and enabled nations to acquire nuclear weaponry (Lisiero, 2008).
