Fair enough, I wasn't super aware of scenarios people mining their own country for defense purposes and I agree that an argument can be made there, as it will not be civilians invading a different country.

As you are aware, in the Balkans this was exclusively done in areas to harm civilians, deep into other countries. I have a plum garden that was near the enemy lines in the 90s, and it was mined. We had to arrange demining squad to go through it, and I still have childhood memories of their tools (mine detectors) being left overnight at our place. Not a memory any person should have.
