World War II allowed countries around the world to see the huge destructive power of atomic bomb . In August 1945, the United States dropped two atomic bombs on Japan, causing Japan to lose its ability to continue combat. Its local heavy industry suffered huge losses and caused 300,000 military and civilian deaths. That was the first time that the atomic bomb was used on the battlefield, and it was the only time until now. With the development of science and technology, nuclear weapon is no longer unique to the United States. Since countries realized the power of nuclear weapons, they have begun to study nuclear bomb .

Russia and India are our neighbors and countries with nuclear weapons. The Soviet Union was the predecessor of Russia. In order to gain hegemony, it launched a decades-long arms race with the United States before its disintegration. During this period, the Soviet Union developed a large number of nuclear weapons. After that, most of these nuclear bombs were inherited by Russia. Now there are 5,977 in service, which is also the country with the largest number of nuclear bombs in the world.

. India announced its possession of nuclear weapons in 1998. In theory, except for the five permanent members of the United Nations that can legally build and hold nuclear weapons, other countries are not allowed to develop, and they cannot hold them. However, because India did not sign the " Nuclear Non-Proliferation Treaty " and publicly stated to the world that it has nuclear weapons , countries around the world have no choice. Moreover, India is also an ally that the United States and Russia want to fight for in the Asia-Pacific region. The two major countries turn a blind eye to it and are unwilling to offend it. After

WWII , Japan, as a defeated country, was not allowed to develop nuclear weapons and build other offensive strategic weapons, such as aircraft carrier , medium- and long-range missiles, etc. However, Japan's research on nuclear weapons has not stopped. For half a century, it has been collecting nuclear waste around the world in order to obtain raw materials for building nuclear weapons, which shows its ambitions.

Japan is the only country that has felt the taste of nuclear weapons. After the war, in order to stabilize its hegemony, the United States also provided economic assistance to it. Japan also became the earliest developed country in Asia, and its economic strength once ranked second in the world. In recent years, Japan has the largest number of nuclear power plants in the world. Although no one knows whether Japan has developed nuclear weapons on the surface, so many nuclear power plants can also show Japan's strong desire for nuclear power. According to data estimated by relevant personnel, the nuclear raw materials held by Japan are enough to create a thousand nuclear bombs.

Japan's earthquake was caused by plate movements in the earth's crust, but Japan has more earthquakes in recent years than before. Some people even suspect that Japan secretly detonated nuclear weapons, and the tests caused frequent earthquakes in Japan. However, whether it is true or false, Japan will not admit that they have nuclear weapons, because once they admit it, they will be subject to international sanctions for . Moreover, it is not surprising that Japan has mastered the nuclear technology . In the world, Japan was the first country to study nuclear weapons, and it was built by the United States first because of the raw material problem.

Japan is also banned from owning the aircraft carrier , but Japan has built 7 quasi-aircraft carrier-class helicopter destroyer . According to various signs, it is not difficult to see how huge Japan's ambition is. After taking advantage of the United States to develop its country's economy, Japan has been working hard to break away from the control of the United States in recent years. In short, Japan must be guarded, and it deserves the world's vigilance.
