What would happen if a nuclear war start?

If there's an outburst in Iran?





North Korea send the Nukes on Japan and South Korea,





The US retaliates , China and Russia enter the nuke game





India and Pakistan start fighting





Things got worst in Iraq and Afghanistan





UEA, Palestine, Jordan and Egypt jump on Israel,





a tsunami happen in the Caribbean


and everyone start fighting .





Would this mean that the end of the world would be near?





If all the nuke countries started a nuclear war, what would happen to the rest of survivors if there is any?|||Total disaster. The rest of the survivors would be a very small amount. In a nuclear war, mass fatalities is imminent, survival is futile. The global disaster would destroy all plant life and cause more damage to the ozone layer, allowing in more of radiation. The survivors nearly about 40-50ft of ground zero where the bomb would drop would probably have at least 15 seconds until the 4,000 degree heat wave would reach and at least 30 until the shock wave does.





But it's not mainly the initial blast that kills people, but the mass radiation. Gamma rays ( deadliest form of radiation) can penetrate body tissue and flesh damaging vital organs and causing cancer. Radiation sickness would spread all over even though it's not contagious. A lot of the earth by the first week of a nuclear war would already be contaminated and a fall out is still out of the question, living underground. Any food left around with opened containers would be contaminated, animals would be too contaminated to eat and life would be unbearable for people to sustain.





It could mark the end of the world as you say. Radiation contamination can spread all over the world, infecting everyone. Maybe within the first 3 weeks or so, survivors would survive but a nuclear war can only last so long. Maybe there's hope? Maybe not. Right now, the world has more than 30x times the nuclear weapons to kill off the human race so it's not so good if a nuclear war starts. Lets hope in our life time, one won't start. But with Iran and North Korea posing a threat, were never safe. A nuclear war does not seem probable at the time but yet, a nuclear war can come at any time with no warning.





Heck, at defcon 1, the U.S. military can be kicking, firing all the nukes they can blast within the first 15 minutes that defcon 1 is issued. Lets just hope your not in the area of ground zero. If your on the other side of the globe, you're probably ok.|||Well pretty much if there were survivers, they would be living in the dark ages. Pretty much starting all over from scratch. They'd have to try and survive and move to areas that wouldn't be contaminated. How they'd find those areas, most probably wouldn't be able to. There would be a lot of fatalities from radiation sickness and cancer. Life may go on, but who knows if the radiation would alter our DNA somehow.|||alot of things would happpen...u would have global warming..and that willl mess with the ozone layer....air willl be polluted.....plants would stop growing..animals would die because lack of food...and then we would proably die..|||youd die *****
