The employment of nuclear weapons in the conclusion of World War II served as a significant influence in world politics. The usage of nuclear weapons in Hiroshima and Nagasaki demonstrated how devastating nuclear weapons could be, transforming the way of war and global security.
Following the war, the United States was in a strong position with its nuclear capability. This changed the state of power and induced tension with the Soviet Union. The power of the military was no longer supported only by the existence of conventional armies but by the capacities of nuclear weapons as well.
The Cold War was caused by the danger of nuclear violence. There was an arms race in which the United States and the Soviet Union tried to build arsenals of larger size. This race compelled nations to incorporate alignments politically and economically and even to the military line which gave shape to post war world politics.
Diplomacy and international relations were affected by the nuclear weapons. The threat of mutual destruction stimulated treaties, such as the Non-Proliferation Treaty. Countries were very careful on the military front, and diplomacy, alliances and political planning were critical in averting disastrous conflicts.
The international political landscape was moving into collaboration and prevention. Countries were concerned with preventing nuclear war and security. Nuclear weapons changed world politics and states had to strike a balance of power, safety and international relationships.
Conclusion
The introduction of nuclear weapons irreversibly transformed the way geopolitics is played out. They reshaped power relations, provoked an armament race, and influenced the way diplomacy has been conducted all over the world. The state policy experimented with deterrence policies, gradual partnerships, and strategic planning, with the threat of nuclear war as the new vehicle of global peace.
