If we ever do have a WWIII,
it won't necessarily be a nuclear war!
If there ever is a WWIII, it will very likely start out, the same way as WWII and a lot of other wars started: Just a regular, conventional war. Two countries will decide they don't like each other. Those countries will grab their guns, tanks, troops, etc, one country will invade the other. Then, those countries will ask for help from their allied countries and possibly even places like the UN.
Once other countries join forces, someone will decide to attack an innocent country that doesn't want to get involved, just like in WWII, Japan messed with the wrong country and got their butt kicked!
If, however, all countries play fair and obey the laws that say you can't use nuclear weapons at all, unless another country launches one at you first, then, no nuclear weapons weapons would be used at all in the first place! In the US, we can use them in retaliation for the use of chemical weapons by another country, against the US.
In fact, ironically, the US and most other countries that have nuclear weapons, including: Russia, Canada, India and China, just to name a few, have them and keep them well maintained and ready at all times to PREVENT WWIII from ever happening in the first place! NOT so that we can fight a nuclear war!
The US invented both Atomic and nuclear weapons.
Atomic bombs ended WWII, but, those are no longer used. Soon after the war, the US invented nukes. Russia soon followed, along with other countries.
Since the US and Russia didn't get along at the time that nukes we're invented, they thought, " since the US has nuclear weapons, we need to have them to, so we can defend ourselves."
The US did not teach Russia how to make nuclear bombs, they had to figure that out themselves. They did!
Once the US found out that Russia had their own nukes now, the US no longer had an advantage and had that much power over the Russians. The Two governments had to have a talk with each other now and they both agreed on one thing:
Mutually Assured Destruction!
The US President told the Russian government, "If you ever launch a nuclear missile on the US, it's over, because, if you launch even one at me, I'll hit you with a whole bunch of nukes!"
The Russian government said, "I understand that. The same applies to you! If you launch one at me, I'll do the same to you! Launch several more than what you launched at me!"
Either way, they both agreed, it would be a bad day and possibly the end of the world! They called it: "Mutually Assured Destruction".
Eventually, other countries learned how to make them to.
Bill Clinton wanted to make some kind of a trade at one time with N Korea. So, of all things he could of chosen to trade, he gave them the plans of how to build a working Nuclear bomb!
Russia eventually created the largest and most powerful nuclear bomb ever: The Tsar Bomba. Much bigger than any US nuke!
Then most countries around the world signed a treat saying that they will no longer test nuclear weapons at all. This includes testing of nukes everywhere: Above ground, under ground, above or under water, suspended or launched into the air or anywhere in outer space.
The problem with a treat, however, is that it is just a piece of paper with signatures on it. Most treaties only last a certain amount of time and they have to be renewed. When one President signs a treat for anything, that ruins things for every President after them! If the next President wants to test nukes, for example, in this case, now they can't, because, a former President signed a treat, making it illegal. Now the next Presidents after the one who signed the contract can't do it. But, they are going to think, "I should be able to do it, because my signature is not on that treaty! I'll find a loophole in the treaty and I'll do it anyway!"
Treaties get violated all the time!
There is a treaty that protects Antarctica. It says that nobody can drill for oil or test nukes or do other potentially harmful things on that continent. Also, nobody, except: Scientists, government officials, military and a few other, similar people are allowed to explore the Antarctic Continent. There are probably a few places where regular, civilian tourists can step foot on the land, just so they can tell their friends they have been to Antarctica and walk around on the ice glacier.
However, the easiest way to win a nuclear war would be to launch 1,000 nukes on Antarctica! That would cause massive flooding, Tsunamis and severe, global warming, just to name a few problems! But, that would kill Everybody in every country, rather quickly!
When you see the President on TV, you often see one person staying close by, with a brief case handcuffed to his wrist. That is because, everything in that brief case is so important, so top secret and would be very dangerous if it got into the wrong hands.
I don't know what all is in there, but, one of the most important and dangerous things in there is: The codes to all the nuclear missiles in the US and all of them that the US has in other countries.
Other countries know that the US President has easy access to the nuclear missile codes at all times, 24-7-365! That is another deterrent to the commies and terrorist countries launching a nuke at us.
The most recent nuclear weapons test is suspected to of been in North Korea, just a few years ago. They deny having ever built and/or tested a nuke. However, the US and a lot of other civilized countries are constantly watching N Korea. We are watching them from outer space, on the and under the ocean, from S Korea and other countries, etc.
It only takes the International Space Station about 90 minutes to completely circle the Earth! Don't you think Astronauts and Russian Cosmonauts could see the big mushroom cloud out the window of the ISS? However, that would be only, if someone were looking out the window at the right time and when they were over N Korea.
The satellites in space could also see it and, in several different countries, including the the US, they have devices that can detect the radiation and other things that are a tell tale sign of a nuclear explosion anywhere in the world. All the nuke detection systems around the world detected a nuclear blast somewhere on Earth. Nobody owned up to it. So it was investigated and, the evidence showed that it came from N Korea.
These days, there are some people who don't like nuclear weapons. They are trying to fight to get rid of them and have every country sign a treaty to get rid of all nukes and never make anymore ever again!
That's not going to happen!
Like I said before, a treaty is just a piece of paper! It is not worth anymore than the paper and the ink that it was signed with!
People and countries violate treaties all the time!
Besides, with so many unethical countries out there that support terrorism and they don't like the US or a lot of other countries, we better have something to defend our country's with!
Some countries, I would never trust, Even if they did sign a treaty like that! They'd sign it, but, still keep some nukes. The US needs to keep some nukes, just to prevent those countries from attacking.
However, there are a few countries that have signed a treat saying that they, in their own country, will not have any nukes. The government and people of those countries agree with and support the ban. Maybe, they are near other countries that do have nuclear weapons. In that case, if a nuclear missile we're launched on their country, it could hit one of those neighboring countries. Even if it hit the intended target, the radiation, fallout, explosion itself, etc would affect the countries next to them, so, those countries would probably retaliate by launching their own nuclear missiles.
