They should use AI driven mini robots that go around and blow up mines.

The rats are already mini, and have real intelligence unlike AI does. They also reproduce cheap. Mines are cheap and numerous, and anything that deals woth them had to be cheap

so, you are indirectly saying intelligent creature are cheaper than machine which uses AI ....

I had several thoughts while reading this article. > Cambodia is contaminated with millions of unexploded ordnances dropped as cluster bombs by the U.S. during the Vietnam War. In addition, millions of land mines were buried throughout the country during a series of civil wars from the 1970s–1990s. Millions. I can't process numbers that large. I know what a million is, but I struggle to imagine what a million land mi…

If you want to learn more about the mines in Camobida I highly recommend the low-budget documentary Until They're Gone[0], which features a small human-based mine removal effort promoted by Landmine Relief Fund[1]. I read an article in the Economist a couple years about the lingering impacts of mines and ordinance in Cambodia, and it struck me heavily and I looked up more information and came across those. It's horrible that all these ordinances are still maiming people decades after a war that their country was hardly even involved in, but there's also a lot of exciting work and progress being made. A mine-free Cambodia really is possible, and in not that many years!

This is a serious question:

In a place like the DMZ, are mines really immoral? Are land mines universally immoral? Anymore than any other weapon of war? Does this immorality extend to naval as opposed to land mines?

No one is walking freely in the DMZ. Certainly not children. If land mines are effective (US generals say no, but they don't win too many wars.) they raise the cost of attack almost for free.

This stabilizes the situation avoiding what would be a devastating war.

Some object that a war that gets rid of the North Korean regime is necessary and not to be avoided. I wouldn't necessarily disagree, but point out that I chose the DMZ merely as a widely known dangerous example. The example can be changed to any border dispute between two "dangerous" countries (say India and Pakistan).

Nor can the "indiscriminate nature" save the argument. A cluster bomb thrown into a city is indiscriminate and a terrible thing. But the immoral act is deploying the weapon where it acts without discretion. This is no different from carpet bombing city a la WW2.

So the question remains: why are land mines malum in se? And how are the uniquely evil compared to any other weapon of war? [1]

[1] Im not being facetious. I believe there are inherently evil weapons, chemical or biological ones come to mind, while other weapons have, if not a nobility to them, are not inherently evil: the rifle.

Land mines persist long after the wars have ended, quietly waiting to maim the innocent.

But this easy to answer. In a war -- as annoying as they are -- the idea generally is to kill precisely the enemy and avoid killing civilians. Once the military is eliminated, then the country surrenders and the war is over.

This is obviously NOT how it really works in practice.

But this is why carpet bombing, phosphor, mines and so on are not precise and deliberate but indiscriminate. Mines particularly persist long after wars, killing people who have presumably made peace or people who were not even involved in the war.

So immoral? Definitely if a mine kills you or someone you know while on a relaxing vacation 40 years after it was planted -- it feels immoral. So immoral? I think so.

Your example of the DMZ is not well chosen. Lots of innocent civilians try to defect across it to South Korea. Killing them with randomly planted mines seems immoral, unless you would like immediate execution of all defectors. Which I find immoral, personally.

I think this is less about the casualties of war itself, but the effects of when trying to move on after the war.

If people die due to landmines many years after a ceasefire are they a casualty of the war?

I think landmines represent a physical device that artifically extends the destruction of war in a time that is way after the parties may have agreed to peace. In that sense, the landmine inflicts death on people with no agency. A bomb dropped on a someone has intent and an army responsible for it. A landmine planted decades ago is so divorced from its original intent that any resulting death or injury feels random and injust.

Ok, thats a strong argument. But, Im not convinced.

For starters, if we assume humans have the ability to solve conflicts like the DMZ we should be able to put a structure in place to prohibit people from going to old mine fields. That is, fundamentally, the basis of nuclear waste storage: the belief that society can create a future political structure to keep humans out of a dangerous place. (I doubt that we can, so Im opposed to nuclear power, and I'll grant that it follows that this is an argument against mines.)

Im not arguing that land mines should be used liberally over large swaths of land. The DMZ is a narrow strip of land. If the Korean dispute ever ends (I have my doubts), it can be made into a nature preserve. Or it can be carefully de-mined over centuries like Europe has been since the wars. Continental Europeans have lived and worked around unstable explosives for over 100 years.

And, as long lasting as land mines are, its not obvious to me that our conflicts can not outlast them (!! I do have faith in our obstinacy). The Korean war is 70 years old, the DMZ is not a dry desert (some border regions are, however). Eventually the materials will crumble and nature will take over.

Finally, the basic question remains unanswered: are the (relatively rare) loss of life and limbs of innocents over decades or centuries worse that a war like the one that would break out between the Koreas? That's not obvious to me.

> I didn't know dogs were used to clear mines. I would have thought they would be too heavy to walk on mines, considering that mines can kill children, and military working dogs have a weight comparable to children. Remember that a dog almost always has two of its paws on the ground. Forgiving for dynamics, if a 50lb child is walking, it could place all 50lbs on a trigger. A 50lb dog should only be able to place 25lb…

Even a light dog can put a surprising amount of pressure through its feet if it wants to. Tiny paws mean it's all concentrated in a small area. My 10kg dog feels like he weighs a ton when he puts his front paws on me and leans into it. I've no idea what it takes to trigger a mine, and I don't know if it would be enough, but a dog can press down harder than you'd expect.

I know what you mean, when they stand on you wrong it's surprisingly heavy. But it's point loaded. A dog doesn't do that while walking around on even-ish ground. The point is it would take unusual scenarios for a dog to get 100% of their weight on one foot, but any toddler does it every step.

I would think this works both ways though. Yes, smaller surface area is bad, but also reduces the chance the dog presses down on a trigger. But then again... they have four feet, but then they a narrower track, but then they probably take more steps. It's complicated I suppose!

That’s just not how explosives work. Any detonator explosive to set of a main charge must be reliable for dozens of good reasons. Over time an as a required condition. Asking for something decays or approaches an unreliable state after time is a non-starter. Another user pointed to a basically failed electronic program, but even then, you have to detonate the mines, you can’t just disarm them and make the highly effi…

So in your post to incorrect others on 'thats not how explosives work' you got absolutely everything wrong about how explosives work. Typical HN. > You wouldn’t ever give your enemy deliveries of repackagable charges. Where did you get this preposterous idea? Do you imagine a major military will send out it's soldiers to collect labdmines on purpose to dissasemble them and take out tiny amount of explosive? And after…

>Do you imagine a major military will send out it's soldiers to collect labdmines on purpose to dissasemble them and take out tiny amount of explosive?

I literally said the complete opposite of that by saying the mines have to self-destruct. They still need to explode. Try another read of the original post.

I worked with an EOD group in OIF. Where do you think IEDs come from? You think farmers and merchants are mixing ANFO in their huts? No, it's all seconardy explosives they we "donate".

Tell me more.

War has many generational effects.

Russia still has periodic fertility gaps from WW2. In Paraguay blond, blue eyed, natives who only speak Guarani are witnesses of the Triple Alliance's widespread rape (150 years ago?). Europe is littered with unexploded ordinance

A landmime is not a pleasant thing to leave behind. But if deployed strategically (not scattered everywhere as a terror weapon), and if it can avoid a war its not obvious to me that the generational effects aren't the least evil.
