I don't like the idea of land mines. They stick around far too long after the event. Dog doo is bad enough.< / totally unqualified opinion >
The U.S., Russia, China, India, North Korea, South Korea, Iran, Israel, and a bunch of others are not signatories, so its not like there's a clear divide in 'good guys' vs. 'bad guys' for those who will use them and those who won't.
Also, little tangential, but they have a picture of an elephant with an artificial leg at the link.
If this were 2009 to 2017, this would be reported...
“Land-mine casualties show signs of global decline” > under Obama.
The Burma/Myanmar army uses them extensively against all of the ethnic minorities. One medic in the resistance once performed 7 successful amputations using a Leatherman Multitool. Men tend to lose their lower leg while women and children typically die on the spot. The Free Burma Rangers lost a brave relief worker to the landmines.
The Burma army will burn a village and then plant landmines in the ashes. Sometimes they will post a notice to a tree and then place the landmine in front of it so those who step up to read the note are killed.
Both sides use mines and they will continue to be used because they work.
How hard would it be to develop a landmine with a finite shelf life? Six months, say.
Well of course, eventually you run out of landmines.
