Nuclear weapons are explosive devices that derive their destructive force from nuclear reactions, either nuclear fission or a combination of fission and fusion. In the alternate timeline, the development and use of nuclear technology has followed a markedly different path compared to the history of the nuclear arms race in our world.
The foundations for nuclear weapons technology were laid in the early 20th century through the work of European physicists like Marie Curie, Enrico Fermi, and Niels Bohr. Atomic research programs first emerged in France, Germany, and Italy in the 1930s, spurred by the looming threat of World War II. These nations viewed nuclear weapons as a means to gain strategic advantage.
In 1942, the German-led Manhattan Project successfully detonated the first atomic bomb, bringing the war in Europe to an abrupt end. This was followed by the use of nuclear weapons by the French against Japan in 1945 and the Italians against China in 1948, demonstrating the destructive potential of this new technology.
In the postwar decades, nuclear weapons gradually proliferated beyond the initial three powers. Spain, Portugal, and Greece all developed their own nuclear deterrents in the 1950s, followed by Sweden, Switzerland, and Austria in the 1960s. Japan, South Korea, and Taiwan also built small nuclear arsenals, citing the need to counter perceived threats from China. Even smaller nations like Israel, South Africa, and Argentina joined the nuclear club in the 1970s.
The existence of these multiple competing nuclear powers reshaped global geopolitics. Conflicts between nations often escalated to include the use of tactical nuclear weapons, such as in the Iberian Wars, the South Asian nuclear exchange, and the Middle Eastern Nuclear Crisis. This proliferation also heightened concerns about the risk of accidental detonation or nuclear terrorism. Efforts to curb the spread of nuclear weapons had limited success.
The widespread availability of nuclear technology has had profound impacts, both positive and negative. On one hand, the energy produced by nuclear fission and fusion has become a major source of power generation globally, helping to reduce dependence on fossil fuels. Civilian nuclear power plants provide electricity to hundreds of millions worldwide.
However, the destructive potential and radioactive fallout of nuclear weapons have also taken a heavy toll. Hundreds of thousands have perished in the nuclear conflicts that have occurred. Long-term environmental damage from weapons testing and nuclear accidents like the Chernobyl disaster is extensive. There are also ongoing debates about the strategic value and moral implications of nuclear deterrence.
Today, over 20 nations are believed to possess nuclear weapons, radically altering the global balance of power and the risks of warfare. While some progress has been made in arms control treaties and deproliferation efforts, the widespread availability of this technology continues to be a source of significant concern and controversy worldwide.
