For all the fear that proliferation creates, there are fewer nuclear powers now than in years past. Some of the nations already gave up with their Nuclear Bombs.
One of them is South Africa. It began a nuclear-weapons program in the 1970s, and later acknowledged completing six nuclear warheads. But with the apartheid-era government under serious international pressure, it became the first country to voluntarily give up its nuclear program. Another one is Brazil, that left the nuclear program because they considered that it would not help them against international relations. Argentina is another one that stepped out because of more pressing domestic security issues. In 1971 Taiwan also gave up after United States pressure and promises to sell Taiwan conventional weapons in exchange. The last one is South Korea. The reason is unclear, but the United States pressure made something about it. Some experts are worried with them, because they can may be lead to a nuclear war with Japan and North Korea.
