These are the user uploaded subtitles that are being translated: 0:01 in August 1945 nuclear war became a 0:05 reality when the United States dropped 0:08 two atomic bombs on cities in Japan 0:10 seven decades later the Arsenal's of the 0:14 great powers are 140,000 times more 0:17 powerful 0:19 what would happen if a nuclear war broke 0:23 out today it will be the worst thing 0:26 ever to happen in human history 0:29 it's the moment people across the world 0:32 have feared for more than 70 years an 0:36 incident between the United States and 0:39 Russia has escalated out of the ten 0:42 thousand nuclear weapons that are in the 0:44 possession of the military roughly 1,800 0:47 are on alert ready to go on top of 0:51 ballistic missiles on very short notice 0:53 the overwhelming amount of nuclear 0:55 weapons on alert our US and Russia the Nuclear War 0:59 US and Russia have missiles both on subs 1:02 and on land land missiles are based deep 1:07 in the heartland of each country and 1:10 while both sides have them in silos only 1:14 Russia deploys mobile launchers 1:17 these weapons are designed to kill and 1:20 destroy on an unsinkable level if you 1:23 make the rocket very large and you can 1:26 make the nuclear warheads very small you 1:29 don't have to limit yourself to just one 1:30 warhead per missile some missiles have 1:36 as many as 10 warheads each 150 times as 1:40 powerful as the bomb that destroyed 1:41 Hiroshima in 1945 in the first strike 1:48 you're gonna have something in the order 1:50 of 600 to 700 ballistic missiles with 1:53 nuclear warheads from both countries 1:56 flying against each other a nuclear war 2:00 the modern age is going to be pretty 2:03 fast a lot of it is gonna be motivated 2:06 by the fact that a lot of our weapons 2:09 are targeting a lot of their weapons and 2:11 vice versa 2:12 so whoever strikes first gets to use 2:14 their weapon if you leave the weapon in 2:17 the silo and they're allowed to hit it 2:20 then you've lost them 2:23 they call this user or losing 2:27 the first cities that would be hid are 2:29 cities that have important military and 2:32 civilian leadership and command 2:34 structure in them Washington DC Moscow 2:40 you would have enormous lead devastating 2:43 consequences in Washington DC the most 2:46 likely targets to be hit very early on 2:49 include the White House and the Pentagon 2:52 is 500 kiloton warhead attack on the 2:56 White House would create a fireball with 3:00 a diameter of one mile you are vaporized 3:03 you are instantly one with the universe 3:08 at virtually the same time as Russian 3:11 bombs hit Washington the US Britain and 3:14 France strike Moscow with 80 warheads 3:17 the city becomes a field of flaming 3:20 wreckage 3:21 and a million people are dead almost 3:24 instantly in Kansas America's heartland 3:28 the first occupants arrive at a unique 3:31 high-end survival bunker 3:35 lavishly outfitted from the remains of a 3:37 silo that once housed an Atlas rocket 3:41 America's first intercontinental 3:44 ballistic missile there are very many 3:46 fallout shelters anymore but people have 3:49 decked out these missile silos into 3:53 these luxury apartments 3:58 they cost more than a million dollars 4:01 they have five years worth of food 4:04 they've got hydroponic growing systems 4:06 and apparently 70 people that's a 4:09 community can live for five years and 4:13 wait for the worst to blow over as the 4:16 war expands worldwide a Russian naval 4:21 commander finds a target of opportunity 4:23 in the southern pacific an American 4:28 aircraft carrier docked in Australia at 4:31 Sydney Harbor 4:34 the Russian commander launches a 4:37 nuclear-tipped cruise missile at it to 4:39 take it out the carrier and it's 6000 4:43 crew members are instantly vaporized 4:48 6,000 miles away american nukes strike 4:51 beijing as the u.s. suspects Chinese 4:55 involvement in the Sydney attack Chinese 4:58 submarines retaliated with nuclear hits 5:03 along America's west coast 5:06 from Seattle to San Diego 5:11 [Music] 5:13 the death toll pushes past 100 million 5:17 as thousands of square miles are left 5:20 smouldering for cities and military 5:22 bases once stood look back at the atomic 5:27 bombs that were dropped on Hiroshima and 5:29 Nagasaki if you just multiply that by 5:32 millions you can imagine the aftermath 5:34 of a global nuclear exchange when Nuclear Winter 5:39 Russian warheads struck American missile 5:41 silos in the northern Mountain States 5:44 radioactive fallout began taking a 5:46 massive toll 5:49 wind patterns would carry it and drop it 5:51 on huge areas of the country so that 5:57 would essentially be no safe place to go 5:59 to have some idea of what's gonna happen 6:02 in the future after these cities are 6:03 ruined think of Chernobyl there were 6:08 cities nearby that were evacuated today 6:16 they're really overgrown with vegetation 6:18 and animals are just roaming freely 6:20 there 6:20 [Music] 6:23 that's what its gonna be across huge 6:26 swaths of North America for example the 6:30 world now settles into a deep gloom as 6:32 the skies go dark the bombs started 6:38 massive fires that sent fifty million 6:40 tons of soot into the air the soot from 6:45 the massive nuclear fueled fires blocked 6:48 so much sunlight that it plunges the 6:51 world into a sudden nuclear winter this 6:57 is an ice age with Fallout with 7:00 radiation everything is going to be 7:03 damaged in some way or another 7:05 scientists say a nuclear winter will 7:08 freeze the earth for about two decades 7:13 the onset of this winter is shocking 7:19 this is a long-term horrible horrible 7:24 catastrophe that would happen in the 7:27 case of a global thermal nuclear war two 7:30 decades later the fiery destruction of 7:33 nuclear war has left half the planet in 7:37 ruins and nearly 90 percent of the 7:43 world's population has died off say a 7:48 handful of people do make it and they're 7:51 in one of these shelters then it's time 7:53 for them to venture back out onto the 7:55 surface 7:57 they will be entering into a completely 8:00 unfamiliar terrain everything they knew 8:03 of would be gone the earth eventually 8:07 begins to thaw from its nuclear winter 8:11 the winds break up the global cloud 8:14 cover letting sunlight back in and the 8:19 planet slowly warms with the passage of 8:24 time the world's decimated population 8:27 grows slowly Aftermath 8:35 a century later the ruins of abandoned 8:39 cities are overgrown by weeds as nature 8:43 eventually reclaims them 8:48 there is little rebuilding in the 8:50 northern hemisphere where the 8:52 destruction was the greatest now the 8:56 real interesting question is what will 8:58 happen with the rest of the world will 9:01 maybe perhaps Brazil rise to power or 9:04 South Africa or even Australia but a 9:08 rise to power will be a slow process a 9:13 city like Rio de Janeiro may not have 9:16 been physically destroyed but so many 9:19 died from starvation that few people 9:22 remain to pick up where civilization 9:24 left off survivors and the warring 9:30 countries become refugees driven to head 9:34 for warmer climates people will migrate 9:39 knowing that perhaps Brazil won't be as 9:41 affected a lot of people are gonna move 9:43 from the states from the barren States 9:45 to Brazil or maybe Australia we already 9:51 see how refugees operate today countries 9:55 are devastated by war and people have to 9:58 leave with nothing but the shirts on 9:59 their back so they walk huge distances 10:03 or they get on a boat and risk their 10:05 life trying to cross a sea that is very 10:09 treacherous but when you have nothing 10:11 left to lose 10:12 you might as well risk it all nobody 10:15 really knows how many people could 10:17 survive a nuclear winter but I'm a 10:20 little bit of an optimist 10:22 they think humans are incredibly crafty 10:25 and we've come a long way since our 10:28 cave-dwelling ancestors we're really 10:31 smart we've got a lot of dis knowledge 10:33 written down the scientific method 10:35 allows us to quickly pick up from where 10:39 we left off we now know how to make 10:41 progress much faster we know how not to 10:46 fool ourselves we'll enough people 10:48 survive we're guessing that between a 10:53 thousand and ten thousand humans would 10:55 have enough of a variety that we could 10:59 kick-start the human race again but if 11:02 they were able to you know hold on and 11:03 survive you could have a birth of a new 11:07 super culture which would be really cool 11:11 [Music] 11:15 you 11:25 you8552
