World War III is the name given to a hypothetical world war, initially supposed to be fought between superpowers with weapons of mass destruction, usually nuclear weapons. Superpower confrontation was deemed to be the major threat in the latter half of the 20th century, where the Cold War saw the capitalist United States face the communist USSR. This conflict was presumed to result in the exterminationIn biology and ecology, extinction is the disappearance of a species or group of species. The moment of extinction is generally considered to be the death of the last individual of that species. In species which reproduce sexually, extinction of a species or technological impoverishment of humanHuman beings are defined variously in biological, spiritual, and cultural terms, or in combinations thereof. Biologically, they are classified as Homo sapiens ( Latin for knowing man , a primate species of mammal with a highly developed brain. In spirituaity.
Such a globally destructive war with such pervasive weapons ranks with asteroidAn asteroid is a small, solid object in our Solar System, orbiting the Sun. An asteroid is an example of a minor planet (or planetoid , which are much smaller than planets. The asteroids are believed to be remnants of the protoplanetary disc which were no impact, a hostile technological singularityIn futurology, a technological singularity is a predicted point in the development of a civilization at which technological progress accelerates beyond the ability of present-day humans to fully comprehend or predict. The Singularity is sometimes used mor, and catastrophic climate changeThe term climate change is used to refer to changes in the Earth's climate. In the most general sense, it can be taken to mean changes over all timescales and in all of the components of climate, including precipitation and clouds as well as temperature. as an " extinction-level eventAn extinction event (also extinction-level event ELE is a period in time when a large number of species die out. The normal background rate of extinctions is about two to five families of marine invertebrates and vertebrates every million years. Since lif".
When asked what kind of weapons World War III would be fought with, Albert EinsteinAlbert Einstein ( March 14 1879 April 18 1955) was a theoretical physicist who is widely regarded as the greatest scientist of the 20th century. He proposed the theory of relativity and also made major contributions to the development of quantum mechanics replied:
Not all scenarios for World War III have begun with the use of nuclear weapons. Operation DROPSHOT, a since- declassified US plan, written in 1947, assumed a long period of conventional war between NATO and the Soviet Union before any nuclear weapons would be employed by both sides. The standard NATO war planning scenario assumed a Soviet attack on West Germany, in which tactical nuclear weapons would be used only if NATO forces were losing. In most war games, NATO forces faced extreme difficulty defending West Germany and used nuclear weapons first.
Deathlands , a science fiction series by James Axler written in the 80s, is set in the United States a hundred years in the future after a nuclear war between the USA and the USSR in 2001 totally wipes out civilization as we know it.Before the collapse of the Soviet Union and end of the Cold War, an apocalyptic war between the United States and USSR was considered likely. The Cuban missile crisis in 1962 is generally thought to be the historical point at which the risk of World War III was closest. Other potential starts have included the following (see External links below for further examples):
Certain sources also state that the Eisenhower Interstate Highway System was specifically designed to contain several sections which were flat and straight, to be used as emergency runways for nuclear bombers. This, however, is an urban legend. The United States Department of Transportation strongly denies that such a purpose exists in the Interstate highway system. However, several other nations, such as Finland and Taiwan have done so.
