  • Human history has been full of

  • battles and wars,

  • some big

  • and some small.

  • But if World War 3 were to happen,

  • it might be humanity's biggest battle yet.

  • Advanced technology,

  • massive troops,

  • and more intensive strategy would all be involved.

  • People have talked about a possible World War 3

  • for decades.

  • It almost started in the 1960s,

  • during the Cold War

  • between Russia and the United States,

  • but thankfully we managed to avoid that.

  • But let's say we

  • aren't lucky enough to avoid it next time.

  • When might World War 3 happen?

  • Well, it's tough to say.

  • A world war could start due to prominent

  • political figures getting killed,

  • intelligence threats

  • or fighting over valuable resources.

  • Talking about it like this makes the

  • chances of a war happening sound likely.

  • But the chances are actually a lot

  • lower than you think.

  • Since 1945,

  • the world has seen many different battles

  • Vietnam, Afghanistan

  • and dozens of different civil wars.

  • We should keep in mind that

  • in order for a world war to happen,

  • it needs to involve the entire world.

  • And the structure of the world has

  • changed even more since 1945.

  • Countries simply aren't as

  • closely allied as they used to be.

  • Militaries are even

  • stronger and more skilled than they were.

  • As in previous world wars it's most likely that

  • millions of people would die,

  • and the Earth would take decades,

  • if not centuries, to recover,

  • especially with some of the weapons

  • and tools countries would be using in todays age.

  • Soldiers on the ground might have exoskeletons.

  • These are a metal frames around the soldier's body that

  • augment their strength.

  • Although this probably won't turn them into Robocop,

  • it would make it easier for soldiers to carry

  • heavy equipment over long distances.

  • Weapons that can bend around corners

  • might also be a possibility.

  • And instead of seeing the war fought in the sea

  • or the sky

  • it could actually be fought in space.

  • Militaries could fight over weaponized satellites

  • that could affect what's below them.

  • Although a lot of this stuff sounds like something out of a sci-fi movie,

  • we should keep in mind that

  • these weapons are scary,

  • and hopefully no one will ever need to use them.

  • After all,

  • things like this are meant to kill people.

  • But there may not be many soldiers on the ground.

  • The war of the future might be fought on computers.

  • Drones, artificial intelligence and robots

  • could be the only things on the battlefield.

  • There's also a chance that

  • acts of war in the future

  • might not involve any violence at all.

  • Hacking into other countries' computers,

  • as well as power grid shutdowns,

  • are all a possibility.

  • And what would this war be about, anyway?

  • It could have to do with resources,

  • specifically water.

  • Since fresh water is such a scarce,

  • yet valuable resource,

  • nations may begin to fight over it as it continues to deplete.

  • Hopefully, World War 3 won't go on forever.

  • So how could it end?

  • Well, one reason,

  • and a main reason why a world war hasn't happened yet

  • has to do with these things.

  • During World War 2,

  • the United States dropped nuclear bombs on Japan,

  • killing over 100,000 people.

  • The cities involved

  • took decades to recover.

  • But the two nukes

  • used in World War 2

  • would pale in comparison

  • to the modern nukes we have today.

  • Oh, and by the way,

  • there are nearly 14,000 nuclear warheads around the world

  • held mostly by America,

  • Russia and China.

  • A nation can have all the resources,

  • people, and strategy they want,

  • but if a nuke gets dropped on them,

  • then it's game over.

  • And if one country drops a nuke,

  • what's to stop another country from doing the same?

  • And then another?

  • And another?

  • And soon, the world would be destroyed.

  • So who would win this war?

  • A full-on World War 3

  • would have a massive impact on the world as a whole.

  • It's safe to say that the world

  • would never be the same.

  • But try not to lose sleep over this.

  • After all, a third world war like this,

  • with dozens of countries involved,

  • is incredibly unlikely to start tomorrow.

  • If two countries get into a fight,

  • it's more likely that

  • other countries that

  • aren't directly involved will stay that way,

  • and let the other nations fight for themselves.

  • Wars are terrible, let's try to avoid them.

  • After a heavy subject like this,

  • I need a bit more fun.

  • I know,

  • what if we jumped into a pool full of stomach acid?

  • May not be fun but,

  • that sounds like a story for another WHAT IF.
