6 days ago · By far the greatest force driving the development of nuclear weapons after World War II (though not by any means the only force) was the Cold War confrontation that pitted the United States and its allies against the Soviet Union and its satellite states. During this period, which lasted roughly from 1945 to 1991, the American stockpile of ...

e. Nuclear warfare, also known as atomic warfare, is a military conflict or prepared political strategy that deploys nuclear weaponry. Nuclear weapons are weapons of mass destruction; in contrast to conventional warfare, nuclear warfare can produce destruction in a much shorter time and can have a long-lasting radiological result.
Critics of nuclear war strategy often suggest that a nuclear war between two nations would result in mutual annihilation. From this point of view, the significance of nuclear weapons is to deter war because any nuclear war would escalate out of mutual distrust and fear, resulting in mutually assured destruction. This threat of national, if not ...

Nine countries currently have nuclear weapons: Russia, the United States, China, France, the United Kingdom, Pakistan, India, Israel, and North Korea. These nuclear powers differ a lot in how many nuclear warheads they have. The chart shows that while most have dozens or a few hundred warheads, Russia and the United States have thousands of them. T...
The number of countries that possess nuclear weapons has never been higher. Only one country — South Africa — entirely dismantled its arsenal. But, as the chart shows, many more states considered or pursued nuclear weapons, and almost all of them stopped. In the late 1970s, more than a dozen countries considered or worked to acquire them. Recently,...
A simple count of the number of warheads, as shown in the previous chart, does not consider that these weapons differ in their explosive power. It also does not consider that not all of them can be used at once. The data shown in the following chart attempts to take this into account. It considers the destructiveness and deployment of nuclear warhe...
The nuclear weapons states frequently tested their warheads in the past, but tests now have almost ended. The chart shows that they peaked in 1962 at 178 tests, mostly conducted by the United States and the Soviet Union. These tests harmedthe environment and people, especially indigenous communities. Tests decreased later during the Cold War and ha...
After killing between 110,000 and 210,000 people in Hiroshima and Nagasaki in 1945, nuclear weapons have come close to being used more than a dozen times again.1 The chart below shows a timeline of such close calls.2We can see that some of them have been accidental, while others have been deliberate. You can learn more in our articleon the risks of...
Countries have sought to reduce the threat posed by nuclear weapons through international cooperation. Most countries have approved the Partial and Comprehensive Nuclear-Test-Ban Treaties, which seek an end to nuclear weapons tests. The same goes for the Nuclear Non-Proliferation Treaty, whose objective is to prevent the spread of nuclear weapons. ...
