I'll never understand how people can look at what happens to a place when you seed it with thousands/millions of landmines and still think "hey that's a good idea, let's do that!"
Just plant a bunch of hidden murder traps and dust off your hands, no need to think of the next generation(s)! And don't even worry about having a plan to ensure the eventual safe disarming and disposal of these fields of bombs, that's someone else's problem!
