Nuclear War AI Simulation - Russia vs NATO

According to a survey prepared by the FAS and NRDC, there are approximately 23,300 nuclear weapons in the world stored at some 111 sites in 14 countries.
stage exchange of strikes
lead - 3 hours, casualties - 2.6 million
After it started, and As the nuclear threshold is crossed, the fighting escalates into a tactical nuclear war in Europe. Russia sends 300 nuclear warheads using aircraft and short-range missiles to hit NATO bases and advancing troops. NATO responds with about 180 nuclear warheads from aircraft.
nuclear war part one - 45 minutes - 3.4 million casualties
When Europe is destroyed, NATO launches a strategic nuclear strike of 600 warheads of U.S. land and submarine missiles aimed at Russian nuclear forces. Before it loses its weapons systems, Russia fires warning shots, responding with missiles launched from launchers, vehicles, and submarines.
nuclear war part two - attack on strategic centers - 45 minute casualties 85.3 million
The main purpose of the first nuclear strike is not to kill as many people as possible, but to destroy the very possibility of a retaliatory or second strike. All means of application have priority targets. These are primarily missile launch silos, military installations, large cities, large industrial plants, dams. If the power industry, the military, the government, if the power generation and transmission facilities are destroyed - the state will be destroyed irreversibly. In order to prevent reconstruction of the other side, Russia and NATO are striking at 30 of the most populated cities and economic centers of each other, using 5-10 warheads in each city, depending on the size of the population.
As a result of the nuclear exchange, the number of direct casualties, including deaths (34.1 million) and injuries (57.4 million), from the series of nuclear exchanges.
Stage 2 nuclear fallout
The horror of radioactive fallout lies in its ability to spread radiation over a wide area, affecting people, animals, and the environment. Exposure to high levels of radiation can cause acute radiation sickness, which can lead to symptoms such as nausea, vomiting, diarrhea, and fatigue. In severe cases, radiation sickness can be fatal.
27 million more people will die.
Stage 3 nuclear winter and famine
The biosphere received such a blow that it is unlikely to recover and return to its original state. The ecosystem of the equatorial zone, which is tuned to almost constant temperatures, will be particularly affected. There, even if forests are not burned, higher forms of life will disappear, apparently, completely or almost completely.
According to scientists, about 5 billion people in 2 years may die as a result of a nuclear war between the U.S. and Russia, which confirms the need for global cooperation to prevent it.
Let's say no to any war! And it is better to create something new than to destroy ourselves."
