How did the Cold War affect the global nuclear non-proliferation regime?

The Cold War significantly shaped the global nuclear non-proliferation regime, leading to the establishment of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT).

The Cold War, a period of geopolitical tension between the United States and the Soviet Union, had a profound impact on the global nuclear non-proliferation regime. The two superpowers were engaged in a nuclear arms race, each striving to outdo the other in terms of nuclear capabilities. This race led to a significant increase in the number of nuclear weapons worldwide, raising fears of a potential nuclear war.

In response to these fears, the international community sought to establish a framework to prevent the spread of nuclear weapons. This led to the creation of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in 1968. The NPT aimed to prevent the spread of nuclear weapons and weapons technology, promote cooperation in the peaceful uses of nuclear energy, and further the goal of achieving nuclear disarmament.

The Cold War also influenced the structure and enforcement of the NPT. The treaty was largely shaped by the interests of the nuclear-weapon states, particularly the US and the USSR, who were keen to maintain their nuclear monopoly while preventing other states from acquiring nuclear weapons. The enforcement of the treaty was also influenced by the geopolitical dynamics of the Cold War. For instance, the US and the USSR, despite their rivalry, often cooperated in enforcing the NPT against states they perceived as threats to their interests.

Moreover, the end of the Cold War led to significant changes in the global nuclear non-proliferation regime. With the dissolution of the Soviet Union, the US emerged as the sole superpower, leading to a shift in the balance of power. This shift had implications for the enforcement of the NPT, with the US gaining greater influence over the regime. The end of the Cold War also led to a decrease in the number of nuclear weapons worldwide, as the US and Russia agreed to significant reductions in their nuclear arsenals.

However, the post-Cold War period also saw new challenges to the nuclear non-proliferation regime. The emergence of new nuclear-weapon states, such as India, Pakistan, and North Korea, posed a challenge to the NPT's goal of preventing the spread of nuclear weapons. Moreover, the threat of nuclear terrorism became a major concern, leading to efforts to secure nuclear materials and prevent them from falling into the wrong hands.

In conclusion, the Cold
