Forty-six years ago today, on September 22, 1979 (August 2, 1979 in the lunar calendar), a mysterious flash appeared in the southern hemisphere. Whether Israel has nuclear weapons has always been debated. The flash event that took place on September 22, 1979 at the junction of the South Atlantic and Indian Oceans is one of the evidence that Israel is suspected of possessing nuclear weapons. What happened to the South Atlantic flash event? This has to start with the Partial Nuclear Test Ban Treaty. From 1945 to 1963, the United States, the Soviet Union, and the United Kingdom carried out many nuclear explosions on the earth. Some of these nuclear tests were conducted on the ground, some were conducted underwater, and some were conducted in the atmosphere. This caused serious damage to the earth's ecological environment. In order to protect the earth's ecological environment and to ease the nuclear arms race between the two sides in the Cold War, on August 5, 1963, the United States, the Soviet Union, and the United Kingdom signed the Partial Test Ban Treaty in Moscow, banning nuclear tests in the atmosphere, underwater, and outer space. Since then, the United States and the Soviet Union have legally restricted themselves from conducting all nuclear tests except underground. In an effort to monitor compliance with the Partial Test Ban Treaty, both the United States and the Soviet Union launched special satellites to detect possible new nuclear test sites and explosions on Earth. From October 1963 to April 1970, the United States launched 12 satellites into space specifically designed to detect nuclear explosions on the ground and in the atmosphere. The satellite system was called the Vela Satellite System. On September 22, 1979, the Vela satellite system detected two flashes in the area between the Prince Edward Islands and the Crozier Islands (about 1800 kilometers away from South Africa), one very bright and the other relatively faint. This phenomenon usually occurs in nuclear explosions. Experts in the United States believe that a nuclear explosion has occurred in the waters. Subsequently, the US Air Force dispatched aircraft to the waters for verification, but later reported that there was no nuclear explosion. Therefore, the flash in the South Atlantic Ocean has become a mystery in the history of the world. On September 22, 1979, not only did American satellites detect a possible nuclear explosion in the southern hemisphere, but the Japanese observatory in the Antarctic also detected a small-scale earthquake in the area where the incident occurred. The explosion was equivalent to 3,000 tons of TNT high explosives. At the same time, the Arecibo Observatory established by Cornell University in Puerto Rico also detected fluctuations in the atmosphere near South Africa, and there was no storm in the area at that time. American scientists believe that a nuclear explosion may have occurred between Prince Edward Islands and the Crozet Islands. Why is the suspected nuclear explosion that occurred near the sea 1,800 kilometers away from South Africa widely believed to be a successful Israeli nuclear explosion? Because Israel and South Africa have cooperated on nuclear weapons programs. On July 1, 1968, the United Kingdom, the United States, the Soviet Union, and other countries signed the Treaty on the Non-Proliferation of Nuclear Weapons. After the signing of the Treaty, only countries that had nuclear weapons before January 1, 1967 were countries that legally possessed nuclear weapons. After that, countries that possessed nuclear weapons and nuclear explosive devices were not recognized as nuclear states. The countries that legally possessed nuclear weapons in the world were the United States, the Soviet Union, China, the United Kingdom, and France. However, Israel and South Africa have been secretly developing nuclear weapons without the supervision of the Soviet Union and the United States. In 1968, American satellites detected Israel's nuclear research base. Israel and South Africa had close cooperation on the nuclear weapons program. In 1977, South Africa successfully built a nuclear explosive device in the Kalahari Desert. Although there are many indications that South Africa successfully exploded its nuclear weapons, South Africa has not publicly admitted to possessing nuclear weapons on any occasion. The fact that South Africa possesses nuclear weapons was made public in the 1990s. In 1990, South African President Frederick William de Clark announced that he would give up nuclear weapons and said that South Africa had seven nuclear bombs in storage. Later, these seven nuclear bombs were indeed destroyed. South Africa became the first country in the world to automatically give up nuclear weapons. Since South Africa has cooperated with Israel on the nuclear weapons program, it is possible that Israel may already have nuclear weapons. South Africa is one of the countries with the richest uranium resources in the world. Israel has advanced technology and a good industrial base. The two countries are very likely to form complementary advantages in the issue of secret research and development of nuclear weapons. According to some government files declassified by the South African government, in 1975, the defense ministers of South Africa and Israel reached a military cooperation agreement on the nuclear warhead project. Some experts in the United States also suspect that the flash that appeared in the South Atlantic Ocean on September 22, 1979 may have been the third nuclear test conducted by South Africa and Israel. Why didn't the US government conduct a careful inspection of the Atlantic flash incident at that time, or make the verification results public? Because in 1980, President Jimmy Carter of the United States wanted to run for the next president. In order to win the election, Carter tried to cover up the truth, which made the Atlantic flash incident a mystery. South Africa officially admitted that it had nuclear weapons in 1990-1991, but refused to admit that it had cooperated with Israel in the nuclear weapons program. South Africa did not admit that the United States covered up the truth. To this day, it is still a mystery whether Israel really has nuclear weapons. Israel even uses suspected possession of nuclear weapons as a strategy to obtain nuclear deterrence against its neighbors at minimal cost. Of course, it is even more impossible to publicly admit or deny that it has nuclear weapons. If Israel's warships have a limited land area, how can the Israelis conduct nuclear tests? In addition to the aforementioned joint nuclear tests through cooperation with South Africa, data on nuclear weapons can also be obtained through computer simulations. There are no winners in nuclear war, nuclear tests will destroy the earth's ecological environment, Israel should sign the Treaty on the Non-Proliferation of Nuclear Weapons, and countries that possess nuclear weapons after January 1, 1967 should take the initiative to eliminate nuclear weapons. South Africa has achieved earth-shattering wins in this regard.
